Embodiment 1

[0040] Embodiment 1: on-the-spot detection stream uranium content in a certain area

[0041] Determination steps:

[0042] Start the real-time quantitative fluorescence heavy metal uranium rapid detector, insert the quartz micro cuvette into the instrument, and preheat it. Draw 0.5 ml of sample solution with the injector, insert the injector into the reagent reaction tube, inject it into the quartz micro-cuvette through the reagent reaction tube, quickly remove the injector, and cover the sample chamber cover, press Press the start button to start the test. After the sample starts to be tested, the test result in ppb will be displayed within 2 minutes, and the test result will be recorded. After the test is completed, remove the quartz micro-cuvette.

Abstract

The invention relates to equipment for quantitatively and rapidly detecting uranium at constant temperature in real time. The equipment comprises a timing temperature controller (1), a detection kit (2) and a heavy metal uranium detector (3) which are sequentially connected. After a sample to be detected is cultivated in the timing temperature controller, the sample is mixed and reacted with a detection reagent to generate signal change, the heavy metal uranium detector monitors the signal change at the constant temperature and transmits the detected data to a built-in information processing device, and the information processing device analyzes the detected data and obtains the uranium content of the sample. The invention also relates to a method for quantitatively and rapidly detecting uranium at constant temperature in real time. The method comprises the following steps: starting detection equipment, and putting a quartz trace cuvette (7) into the detection equipment; putting the sample to be detected into a slot of the timing temperature controller (1), and cultivating at the constant temperature of 37 DEG C for 5 minutes; sucking a sample solution through a sample injector (6), connecting the tail end of the sample injector with a reagent reaction tube (5) in which a uranium detection reagent (4) is arranged, injecting the sample into the quartz trace cuvette (7) through the reagent reaction tube (5), starting the test, and accurately displaying the detection result in real time. According to the equipment and method, the problem that the heavy metal uranium content cannot be rapidly detected in the field can be solved.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to an on-site rapid detection device and method for heavy metal uranium. Background technique [0002] In recent years, nuclear energy has become more and more widely used. For safety considerations, real-time on-site monitoring of heavy metal uranium content in groundwater, surface water, seawater, wastewater, and soil around nuclear power plants or nuclear waste storage sites has become an urgent need for human beings. However, the current existing technology can only rely on large-scale laboratory equipment such as ICP-MS, ICP-AES, etc. to detect heavy metal uranium. Rapid detection to monitor uranium content in real time and on-site. [0003] The invention uses the principle of heavy metal enzyme catalysis and fluorescent labeling technology to provide a detection device and method capable of quantitatively detecting the content of heavy metal uranium on site. Conten...
