Background
In the field of nuclear industry, workers in the spent fuel post-processing process are in the radioactive environment of radioactive nuclides for a long time, and the rays generated by the radioactive nuclides can damage human cells, so that the incidence rate of cancers can be increased.
Therefore, it is necessary to estimate the irradiation dose in the body of the worker during the spent fuel reprocessing. The radionuclide can be discharged from urine along with the metabolism of a human body, the existing method for estimating the irradiation dose is to collect the urine of a worker and analyze the urine, and the analysis of the urine can be generally divided into four steps: 1. pretreating a sample; 2. chemical separation and purification; 3. preparing a source by electrodeposition; 4. and (6) measuring. The sample pretreatment process comprises two steps of heating digestion and stirring coprecipitation.
The specific steps of the sample pretreatment refer to the analysis method of plutonium in urine approved by the Ministry of health of the people's republic of China, and the specific process is as follows: taking 750mL urine sample, adding concentrated HNO310mL、5mL 30％H2O2Boiling in a heating furnace, maintaining for 20min, transferring into 80 + -5 deg.C constant temperature water bath, adding concentrated H3PO42mL, stirring, adding ammonia water at the rotation speed of 1000-1500 rpm, adjusting the pH value to 8-9, stirring for 20min, and standing for precipitation.

At present, instruments on the market, which replace manual operation, can only realize single functions, such as extraction function, concentration function or purification function, and cannot completely perform the steps of sample pretreatment.
Therefore, urgent need among the prior art is a coprecipitation device that can replace the manual work to carry out urine pretreatment, and it can avoid operating personnel to endure the peculiar smell and can carry out the pretreatment simultaneously to the multiunit urine under the prerequisite of guaranteeing to satisfy the job requirement simultaneously.
