Embodiment 1
[0076] In this example, the above-mentioned experimental equipment and collection mode 1 were used for experimental operation, and the specific parameters were: the sample contained 61g / L U, 1.0×10 -4 g / L Np, 4×10 -7 g / L Pu and 3mol / L HNO 3 , the reagent is HNO 3 、HON 3 -HF and H 2 C 2 o 4 、H 2 O. The specific steps are as follows:
[0077] (1) Take 1ml of sample, add 0.2ml ferrous sulfamate reducing agent and put it into the sample bottle, place the sample bottle on the sample bottle holder;
[0078] (2) Turn on the device, start the separation software, and the software running program is:
[0079] a pretreatment with 5ml HNO 3 Add to the extraction column 1 at a flow rate of 1mi / min, and wait for 4 seconds;
[0080] b Adding samples Add 2ml of sample into the extraction column 1 at a flow rate of 1ml / min, and wait for 4 seconds;
[0081] c rinse with 10ml HNO 3 Add to the extraction column 1 at a flow rate of 1ml / min, and wait for 4 seconds;
[0082] d Elution ...
Embodiment 2
[0095] In this embodiment, the above-mentioned experimental equipment and collection mode 3 are used for experimental operation. The specific parameters are: the sample is 16.2ng / ml plutonium solution (3M nitric acid system), and the reagent is HNO 3 、HON 3 -HF and H 2 O. Specific steps are as follows:
[0096] (1) Take 0.3ml of sample in a 5ml sample bottle, add 0.1ml of 0.5M ferrous sulfamate, shake slightly evenly, and place it in the sample position of the sample bottle holder;
[0097] (2) Turn on the device, start the separation software, and the software running program is:
[0098] a pretreatment with 5ml HNO 3 Add to the extraction column 1 at a flow rate of 1mi / min, and wait for 4 seconds;
[0099] b Adding samples Add 2ml of sample into the extraction column 1 at a flow rate of 1ml / min, and wait for 4 seconds;
[0100] c Elution with 1ml HNO 3 - HF is added to the extraction column 1 at a flow rate of 1ml / min, the collection tube is at position 1, and wait fo...
