CL-P204树脂对^(210)Bi吸附性能研究

Study on Adsorption Properties of ^(210)Bi for CL-P204 Resin

为了解决^(210)Bi测量过程中^(210)Pb干扰问题,选择CL-P204萃淋树脂进行实验研究,实现了^(210)Pb和^(210)Bi有效分离。结果表明:^(210)Pb和^(210)Bi混合液经过树脂吸附和解析后,可快速将约90%的^(210)Bi单独分离出来,且误差小于10%,本方法不但极大地缩短了分析时间,而且提高了分析精度;利用CLP204萃淋树脂分离^(210)Bi,可以有效避免^(210)Pb对测量过程的干扰。

In order to solve 210Pb interference problem during 210Bi measurement,select CL-P204 extraction resin for experimental study,achieve efficient separation of 210Pb and 210Bi. The results show that 210Pb and 210Bi liquids can be rapidly separated by about 90% 210Bi after resin adsorption and analysis,and the error is less than 10%,the method not only greatly shortens the analysis time,but also improves the analysis accuracy,the use of CL-P204 extraction resin to separate 210Bi can effectively avoid the interference of 210Pb to the measurement process.
