Embodiment 1
[0021] (1) Preparation of lead-bismuth mixed standard solution: first divide 0.5mL of 1mg / mL lead standard solution into a 100mL volumetric flask, then divide 0.5mL of 1mg / mL bismuth standard solution into the same 100mL volumetric flask to deionize Dilute to volume with water, shake well and set aside. This step obtains the standard solution of the analyte element whose content of lead and bismuth is 5mg / liter, and the standard solution of the analyte element is used for making the working curve.
[0022] (2) Dispense 5mL of the decontamination solution before cleaning the parts into a 25mL volumetric flask, dilute to the mark with deionized water, shake well and set aside. This step yields sample solution one.
[0023] (3) Dispense 5mL of the decontamination solution after cleaning the parts into another 25mL volumetric flask, dilute to the mark with deionized water, shake well and set aside. This step yields sample solution II.
[0024] (4) Set the following measurement ...
Embodiment 2
[0042] (1) Preparation of lead-bismuth mixed standard solution: first divide 1mL of 1mg / mL lead standard solution into a 100mL volumetric flask, then divide 1mL of 1mg / mL bismuth standard solution into the same 100mL volumetric flask, dilute with deionized water to the mark, shake well and set aside. In this step, a standard solution of the analyte element with a lead and bismuth content of 10 mg / liter is obtained, and the analyte element standard solution is used for making a working curve.
[0043] (2) Dispense 10mL of the decontamination solution before cleaning the parts into a 50mL volumetric flask, dilute to the mark with deionized water, shake well and set aside. This step yields sample solution one.
[0044] (3) Dispense 10mL of the decontamination solution after cleaning the parts into another 50mL volumetric flask, dilute to the mark with deionized water, shake well and set aside. This step yields sample solution II.

Embodiment 3
[0063] (1) Preparation of lead-bismuth mixed standard solution: first divide 0.2mL of 1mg / mL lead standard solution into a 100mL volumetric flask, then divide 0.2mL of 1mg / mL bismuth standard solution into the same 100mL volumetric flask to deionize Dilute to volume with water, shake well and set aside. This step obtains the analyte element standard solution with lead and bismuth content of 2mg / liter, and the analyte element standard solution is used to make the working curve.
[0064] (2) Dispense 5mL of the decontamination solution before cleaning the parts into a 50mL volumetric flask, dilute to the mark with deionized water, shake well and set aside. This step yields sample solution one.
[0065] (3) Dispense 5mL of the decontamination solution after cleaning the parts into another 50mL volumetric flask, dilute to the mark with deionized water, shake well and set aside. This step yields sample solution II.
