Description

Technical Field

[0001] The utility model relates to the technical field of test papers, in particular to a test paper. Background Art

[0002] With the continuous development of my country's economy, the amount of sewage discharged from various industries has increased significantly year by year, resulting in an increase in the content of persistent organic pollutants in water bodies. At present, the methods for treating persistent organic matter mainly include physical methods, biological methods, and advanced oxidation technologies, among which advanced oxidation methods are one of the main research directions of industry insiders. Among the many advanced oxidation methods, the efficiency of peracetic acid in degrading typical organic pollutants and its activation research have attracted widespread attention from scholars at home and abroad. Peracetic acid has high efficiency in disinfection and sterilization and is widely used in medical, aquaculture and other fields. At the same time, the strong oxidizing property of peracetic acid (E0= 1.76V) is used to degrade organic pollutants in water treatment. Considering the need to analyze the effective utilization rate and disinfection effect of the oxidant, the concentration of peracetic acid needs to be monitored. At the same time, if the residual concentration of peracetic acid is too high, it will cause potential harm to the organisms in the receiving water body.

[0003] Therefore, the determination of peracetic acid concentration is essential, but these peroxy organic acids are volatile and will release peroxy radicals under certain conditions, which may cause certain harm to human health. Regarding the harm to the human body, most peroxy organic acids have a strong irritating effect on the skin, eyes and mucous membranes. Long-term skin contact or splashing into the eyes may cause damage. The vapors of some peroxy organic acids are irritating and may cause headaches after inhalation, similar to the symptoms of alcohol poisoning. In addition, some peroxy organic acids have an unpleasant odor, and some even damage the function of brain glands and even have carcinogenic effects. Therefore, when testing these peroxy organic acids, try to reduce the volatilization of organic acids as much as possible to ensure the health of the testers. Utility Model Content

[0024] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0025] Please refer to Figures 1 to 4 As shown, a test paper of the utility model comprises a box body 1 and a test strip 2;

[0026] The box body 1 includes a short box 11 and a long box 12. A first blind groove 13 is provided on the side wall of the short box 11 facing the long box 12; a second blind groove 14 is provided on the side wall of the long box 12 facing the short box 11; when the short box 11 is connected to the long box 12, the first blind groove 13 and the second blind groove 14 form a closed accommodating space, and the test strip 2 is arranged in the accommodating space and one end is connected to the second blind groove 14;

[0027] An outer ring groove 15 is provided on the outer circumference of the side wall of the long box 12 facing the short box 11, a flexible glue layer is provided on the surface of the outer ring groove 15, and a tearable isolation film is provided on the flexible glue layer;

[0028] An inner ring groove 16 is formed on the side of the first blind groove 13 facing the long box 12. The inner ring groove 16 is sleeved on the isolation layer and has an interference fit with the flexible glue layer.

[0029] The long box 12 is provided with a transparent observation window 3 .

[0030] As can be seen from the above description, by setting the short box 11 and the long box 12, the first blind groove 13 and the second blind groove 14 can be combined into a closed accommodation space, which is convenient for the test strip 2 to be set therein; when in use, the short box 11 is separated from the long box 12. Since the test strip 2 is set in the accommodation space and one end is connected to the second blind groove 14, the test strip 2 can extend one end to contact the peroxy organic acid or the substance containing the peroxy organic acid. After contact, the tearable isolation film is immediately torn off to release the flexible glue layer. It is exposed to the outside and is sleeved on the isolation layer through the inner ring groove 16 and has an interference fit with the flexible glue layer, so that the short box 11 squeezes the flexible glue. Combined with the interference fit, a sealing ring-like effect is achieved, and at the same time, it can prevent the long box 12 and the short box 11 from being separated and causing leakage, and avoid the volatilization of peroxy organic acid during the detection process to affect the health of the test personnel, and the test strip 2 extending out of the second blind groove 14 can be directly tested, without the need to use the bottom end of the dropper to extend into the catheter and then add the sample solution, thereby improving efficiency.

[0031] Furthermore, a smooth coating is provided on the surface of the isolation membrane.

[0032] It can be seen from the above description that, by providing the smooth coating, the short box 11 and the long box 12 can be fixedly matched when not in use.

[0033] Furthermore, the surface of the box body 1 is a frosted surface.

[0034] From the above description, it can be seen that the frosted surface can increase the friction, making it easier to open or close.

[0035] Furthermore, the edge of the short box 11 away from the long box 12 and the edge of the long box 12 away from the short box 11 are rounded.

[0036] From the above description, it can be seen that the rounded ends can be easily pressed to avoid injuries to operators caused by sharp edges during squeezing.

[0037] Furthermore, a plurality of anti-slip strips 17 are provided on the surface of the short box 11 .

[0038] It can be seen from the above description that the anti-slip grooves on the short box 11 can facilitate the removal and installation of the short box 11.

[0039] Furthermore, a transparent sealing film is provided on the observation window 3 .

[0040] Furthermore, a transparent sealing plate is provided on the observation window 3 .

[0041] Furthermore, a chamfer 18 is provided on the edge of the inner annular groove 16 .

[0042] It can be seen from the above description that the chamfer 18 can facilitate installation.
