[0002] Sample pretreatment is crucial for ensuring the accuracy of analytical data. However, in the analysis of radioactive samples (such as uranium-containing samples), the high radioactivity of the samples and the interference of radioactive matrix (such as uranium matrix) with the determination of other trace elements necessitate the removal of radioactive matrix during sample pretreatment.

[0003] Currently, extraction and rinsing devices are commonly used to remove radioactive matrix from radioactive samples. However, during the use of existing extraction and rinsing devices, it is unavoidable that the rinsing process will slow down or even stop, which seriously affects the efficiency of analysis and detection.

[0036] Example 1

[0037] Embodiments of this application disclose a separation device 100 for radioactive waste liquid, such as... Figure 1 As shown, the device includes at least one separation component, at least one connector, and a pressurizing component. Each separation component has a communicating separation chamber and a storage chamber. The separation chamber is used to contain separation resin, and the storage chamber is used to store eluent. The connector is correspondingly disposed on the separation component and located on one side of the storage chamber. The connector has a through-hole pressurizing port. The pressurizing component is detachably connected to the connector, and the pressurizing component can deliver a pressurized medium to the storage chamber through the pressurizing port.

[0038] In this embodiment, the separation device 100 includes at least one separation component, at least one connector, and a pressurizing component. The separation component includes a communicating separation chamber and a storage chamber. The connector has a through-hole pressurizing port communicating with the storage chamber. The pressurizing component is detachably connected to the connector and can output a pressure medium. The pressure medium is transmitted to the storage chamber through the pressurizing port to pressurize the rinsing solution, accelerate the rinsing speed of the radioactive waste liquid, effectively solve problems such as slowed rinsing and stagnation, and quickly obtain the analytical solution to be analyzed after removing the radioactive matrix, thereby improving the analytical detection efficiency. Simultaneously, it avoids interference from direct contact with the radioactive waste liquid through stirring, eliminates the possibility of introducing other contaminants due to stirring, minimizes the possibility of radioactive contamination, reduces the amount of radioactive waste generated, and ensures the accuracy of the detection of the analytical solution.

[0039] Specifically, such as Figure 1 As shown, there is at least one separation component, and the number of connectors corresponds one-to-one with the number of separation components, meaning each separation component is equipped with one connector to meet the sealing requirements of the liquid storage chamber in each separation component. The separation chamber contains separation resin, including UTEVA resin. The liquid storage chamber is located at the top of the separation chamber and is connected to it, allowing the eluent to flow from the storage chamber into the separation chamber.

[0040] The liquid storage chamber has an open end on the side opposite to the separation chamber. A connector is located at the open end of the liquid storage chamber to achieve a seal. The connector has a through-hole pressurization port that communicates with the liquid storage chamber.

[0041] Specifically, the pressurizing component is detachably connected to the connector, and the pressure medium generated by the pressurizing component can be delivered to the liquid storage chamber through the pressurizing port, and then flow into the separation chamber. It is conceivable that the pressure medium can be air or liquid.

[0042] In one feasible approach, such as Figure 1 , Figure 2 and Figure 3 As shown, the pressurization assembly includes a pressurizer, a hose, and a function switch 403. One end of the hose is mounted on a connector and connected to the pressurization port, while the other end is connected to the pressurizer. The function switch 403 is located on the hose.

[0043] In this embodiment, the pressurization assembly includes a pressurizer, a hose, and a function switch 403. The pressurizer generates a pressurized medium, and the hose connects the pressurizer and the pressurization port to achieve orderly delivery of the pressurized medium. The function switch 403 is located in the hose and is used to turn on and off the delivery of the pressurized medium to the separation assembly. The function switch 403 allows for regulation of the pressurized medium delivery. For example, when the rinsing rate is normal and there is no stagnation, the function switch 403 can be in the off state. It also allows for switching of the pressurizer. When the rinsing rate slows down, the function switch 403 is turned on, allowing the pressurized medium to be quickly delivered to the separation assembly, effectively increasing the rinsing rate.

[0044] In one feasible approach, such as Figure 1 , Figure 2 and Figure 3 As shown, the hose system includes at least one first hose 401 and one second hose 402. One end of the first hose 401 is connected to a pressurization port. One end of the second hose 402 is connected to a pressurizer. A function switch 403 is located between the first hose 401 and the second hose 402.

[0045] In this embodiment, the hose pipeline includes a first hose 401 and a second hose 402. The first hose 401 is connected in series with the pressurization port and the function switch 403, respectively, and the second hose 402 is connected in series with the function switch 403 and the pressurizer. Along the direction of pressure medium delivery, the pressurizer, the second hose 402, the function switch 403, the first hose 401, and the connector are connected respectively.

[0046] The function switch 403 includes multiple pressure-conducting interfaces, and the on / off state of these interfaces is controllable. When the number of separation components is n, the number of first hoses 401 is also n. Of the m pressure-conducting interfaces of the function switch 403, n pressure-conducting interfaces are in the conducting state, where m and n are positive integers, and m ≥ n.

[0047] Specifically, a pressurizer can achieve pressurized rinsing of multiple separate components through a second hose 402 and a function switch 403.

[0048] Example 2

[0049] Based on Example 1, considering that ordinary pressurization devices, once applied to radioactive analysis laboratories, involve related power supplies and electric devices, will bring a lot of contamination problems, in other words, radioactive analysis laboratories should not use automated instruments and equipment with overly complex functions and high configuration requirements.

[0050] Based on the basic requirements of radioactive analysis recommendations, convenience, efficiency, safety, and reliability, the specific structure of the pressurizer is described in Example 2.

[0051] In one feasible approach, such as Figure 4 As shown, the pressurizer includes a bulb syringe 404, the air outlet of which is pressed and connected to a flexible hose.

[0052] In this embodiment, the pressurizer includes a bulb syringe 404, the air outlet of which is tightly connected to the hose. The experimenter can pressurize the liquid storage chamber by manually squeezing the bulb syringe 404, thereby alleviating the situation of temporary rinsing slowing down or stopping.

[0053] At the same time, the 404 syringe bulb can also achieve back suction, which loosens the separation resin in the separation component.

[0054] In one feasible approach, such as Figure 1 , Figure 5 As shown, the pressurizer includes a bottle 405, the outlet of which is connected to a flexible tubing, and the height of the bottle 405 relative to the separation chamber is adjustable.

[0055] In this embodiment, the pressurizer also has the function of continuously supplying a pressurized medium. For example, the pressurizer includes a small-volume hydraulic compressor or a small-volume automatic air compressor. The small-volume hydraulic compressor can be a drip bottle 405.

[0056] When the pressurizer is bottle 405, bottle 405 can be filled with liquid. The type of liquid can be selected according to the separation requirements; for example, eluent can be injected during the rinsing stage, and eluent can be injected during the elution stage. The outlet of bottle 405 is connected to a flexible tubing, allowing the liquid to flow into the separation chamber to achieve pressurized rinsing. Specifically, the eluent includes nitric acid solution. The eluent includes deionized water and disodium ethylenediaminetetraacetate solution.

[0057] It should be noted that when the height of the drip bottle 405 relative to the separation chamber is adjusted, the pressure of the liquid flowing from the drip bottle 405 into the separation chamber will also be adjusted accordingly. The experimenter can adjust the relative height between the drip bottle 405 and the separation chamber according to the current rinsing rate. Specifically, the drip bottle 405 can be hung higher to increase the water column height and thus increase the water pressure.

[0058] In one feasible embodiment, the drip bottle 405 includes a rinsing drip bottle and an elution drip bottle, one of which is connected to a flexible tubing.

[0059] In this embodiment, the drip bottle 405 includes a rinsing drip bottle and an elution drip bottle. The rinsing drip bottle is used in the initial rinsing stage, and the elution drip bottle is used in the subsequent elution stage. Controlled by the function switch 403, the experimenter can select one of the rinsing or elution drip bottles to connect to the tubing according to the experimental progress. The rinsing and elution drip bottles can not only store sufficient amounts of the corresponding liquids but also continuously accelerate the rinsing and elution processes, and enable rapid switching of liquid types between different stages.

[0060] In one feasible approach, such as Figure 1 and Figure 5 As shown, the drip bottle 405 includes a bottle body, an air conduit, and a filter membrane. The bottle body has a liquid outlet. One end of the air conduit is connected to the bottle body. The filter membrane is disposed at the other end of the air conduit.

[0061] In this embodiment, the drip bottle 405 includes a bottle body, an air conduit, and a filter membrane. The bottle body has a liquid outlet, through which liquid can flow out and enter the liquid storage chamber via the second hose 402, the function switch 403, and the first hose 401.

[0062] One end of the air duct is connected to the bottle body, and the filter membrane is set at the other end of the air duct. During the dripping process, the air in the environment can pass through the filter membrane and enter the bottle body, so that the air pressure on the surface of the liquid in the bottle body is equal to the external air pressure, allowing the liquid to be transported to the storage chamber.

[0063] Example 3

[0064] Based on Embodiments 1 and 2, and considering the issues of reliable connection and adaptation between the connector and the separation component, Embodiment 3 describes the specific structure of the connector.

[0065] In one feasible approach, such as Figure 6 As shown, the separation assembly includes a chromatography column 201 and a reservoir column 202. The chromatography column 201 has a separation chamber. The reservoir column 202 is disposed at one end of the chromatography column 201. The diameter of the chromatography column 201 is smaller than the diameter of the reservoir column 202. The reservoir column 202 has a reservoir chamber.

[0066] In this embodiment, each separation component includes a connected chromatography column 201 and a reservoir column 202. Specifically, the chromatography column 201 is a thin, straight cylindrical chromatography column 201 with a switch. Preferably, the chromatography column 201 is made of polytetrafluoroethylene (PTFE).

[0067] A storage column 202 is positioned at the top of the chromatography column 201. The diameter of the storage column 202 is larger than that of the chromatography column 201, and the storage column 202 is used to store the eluent. Under the influence of gravity, the eluent at the top flows from top to bottom, passing through the separation resin packed inside the chromatography column 201.

[0068] In one feasible approach, such as Figure 1 and Figure 2 As shown, the connector includes a connecting cap 301, which is threaded onto the liquid storage column 202.

[0069] In this embodiment, the connector includes a connecting cap 301, which enables a sealed connection with the top of the liquid storage column 202. The connecting cap 301 has an internal thread, and the outer wall of the liquid storage column 202 has an external thread. The connecting cap 301 and the liquid storage column 202 are connected by the internal and external threads, ensuring convenient disassembly and reliable connection.

[0070] It is understandable that the connecting cap 301 is adapted to the diameter of the liquid storage column 202, thereby sealing the open end of the liquid storage column 202.

[0071] In one feasible approach, such as Figure 3 As shown, the connector includes a flexible element 302 and a fastener. The flexible element 302 is wrapped around the liquid storage column 202. The fastener is disposed on the flexible element 302 and connected to the liquid storage column 202.

[0072] In this embodiment, when the diameter of the liquid storage column 202 is not fixed, the connector is a flexible member 302 made of flexible sealing material. The flexible member 302 can cover the top of the liquid storage column 202, thereby sealing the open end of the liquid storage column 202.

[0073] It is worth noting that the area of ​​the flexible element 302 is larger than the area of ​​the open end of the liquid storage column 202. When a portion of the flexible element 302 covers the open end of the liquid storage column 202, the other portion of the flexible element 302 will hang down onto the outer wall of the liquid storage column 202. The fastener is surrounded on the outer wall of the liquid storage column 202, and the hanging portion of the flexible element 302 is sandwiched between the fastener and the liquid storage column 202, so that the flexible element 302 stably seals the liquid storage cavity.

[0074] Specifically, fasteners include elastic tensioning components, such as rubber. Fasteners achieve positional stability of the flexible component 302 and seal of the liquid storage cavity through compression, tension, and other methods.

[0075] The connector, consisting of flexible component 302 and fasteners, has a wide range of applications and can be matched with liquid storage columns 202 of different diameters within a certain range. Through the combination of flexible component 302 and fasteners, it can meet the pressure rinsing requirements of different separation components.

[0076] In one feasible approach, such as Figure 1 and Figure 2 As shown, the separation device 100 also includes a liquid inlet and a liquid inlet pipe 501, with the liquid inlet being disposed through the connector. The liquid inlet pipe 501 is disposed on the connector and communicates with the liquid storage chamber through the liquid inlet.

[0077] In this embodiment, the connector is also provided with a liquid inlet, which is spaced apart from the pressure port. When the liquid storage chamber needs to be replenished with rinsing fluid, the rinsing fluid can be added to the liquid storage chamber through the liquid inlet pipe 501 and the liquid inlet. Specifically, the liquid inlet is provided on the connecting cover 301.

[0078] Example 4

[0079] In one specific embodiment, the method of using the radioactive waste separation device 100 disclosed in this application includes the following steps:

[0080] Step 11: Use wet packing to add the separation resin to the separation chamber. The filling length of the separation resin is about 12cm. Add the eluent to the storage chamber for preliminary rinsing and wait for the separation resin to pre-equilibrate.

[0081] Step 12: Add the radioactive waste liquid (containing uranium radioactive sample solution) into the storage chamber, wait for all the sample solution to enter the separation resin, and then add rinsing solution into the storage chamber for rinsing.

[0082] During the rinsing process, based on the drip rate of the solution to be analyzed precipitated at the bottom of the chromatography column 201, the experimenter can determine whether the current rinsing rate has slowed down or stopped. If so, the following steps will be taken.

[0083] Step 13: Place the connecting cap 301, which includes the liquid inlet and the first hose 401, onto the liquid storage column 202 and tighten it. Connect the function switch 403 and the second hose 402 to the first hose 401.

[0084] Step 14: Press the air outlet of the pressurizer (such as the bulb syringe 404) tightly onto the second hose 402.

[0085] Step 15: Manually control the pressure until the elution slowdown or stagnation in the chromatography column 201 is significantly improved.

[0086] Step 16: If the rinsing fluid in the storage chamber is insufficient, the switch on the liquid addition tube 501 can be opened directly to add liquid through the corresponding dropper.

[0087] Step 17: Collect the solution to be analyzed and perform detection and determination.

[0088] Step 18: After collecting the analytical solution, the elution buffer can be used for processing. During the process, pressure can be applied using a pressurizer to speed up the elution process (without affecting the analytical results). After elution, pre-equilibrate and wait for the next liquid sample.

[0089] Repeating the above operations can continuously improve situations where rinsing slows down or stops, and can also accelerate operations such as uranium elution from the matrix rinsing solution.

[0090] For the connector consisting of flexible element 302 and fasteners, it can be generally applied to separation components of different sizes and diameters. The operation steps are basically the same as those described above. The only special feature is that the lower end of flexible element 302 can be fastened with corresponding fasteners to achieve a sealed and airtight seal.

[0091] Example 5

[0092] In another specific embodiment, the method of using the radioactive waste separation device 100 disclosed in this application includes the following steps:

[0093] Step 21: Use wet packing to add the separation resin to the separation chamber. The filling length of the separation resin is about 12 cm. Add the eluent to the storage chamber for preliminary rinsing and wait for the separation resin to pre-equilibrate.

[0094] Step 22: Add sufficient rinsing solution (such as nitric acid rinsing solution) to the rinsing drip bottle and sufficient eluent (such as deionized water if only uranium matrix is ​​used) to the elution drip bottle, and hang them up high.

[0095] Step 23: Add the radioactive waste liquid (uranium-containing radioactive sample solution) into the storage chamber and wait for all the sample solution to enter the separation resin.

[0096] First, turn on the elution bottle using function switch 403 to start elution, remove the first 3 mL of solution eluted from column 201, and then collect 10 mL of the solution eluted from column 201 for analysis.

[0097] Step 24: Switch between the rinsing and elution bottles using function switch 403, open the elution bottle (keeping the height of bottle 405 the same or the net height of the liquid conduit the same), and start eluting the uranium matrix until the yellow uranium band on the chromatography column 201 disappears, and continue elution for a period of time.

[0098] Step 25: Switch function switch 403 again, turn on the rinsing drip bottle, pre-balance again, and wait for the next sample.

[0099] Step 26: Open the liquid filling tube 4, add the radioactive waste liquid directly, and then repeat steps 23 and 24.

[0100] The above operation method is a pressurized operation after the relevant device has been solidified, which is suitable for batch analysis of radioactive samples and can significantly improve the rinsing speed.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
