摘要
目的：对生物材料中铊的微分电位溶出分析方法进行研究。方法：0.06 mol/L醋酸-0.05 mol/L醋酸钾作为支持电解质,微分电位溶出测定。结果：本法测定的线性范围3～100μg/L,加标回收率为86.1%～93.3%,方法的相对标准偏差为3.5%。结论：用本法对中毒兔肝、肾、肺中的铊含量进行了测定。方法操作简单、准确、快速,应用国产仪器,便于推广应用。
Objective：It is a reliable method to analyze and study the thallium in biomaterials. Methods：The electrolyte is 0. 06 mol/L CH3 COOH -0. 05 mol/L CH3 COOK, and with potentiometric stripping analysis to detect. Results：h has a good linearity when the contents of paraquat in 3 - 100 μg/L The variable coefficients are3.5% , with average recovery rate between 86. 1% -93.3% at different spiking level. Conclusion： It is proved that this method is simple and fast and with high sensitivity. And it can meet the need of detection thallium in liver, kidney and pulmonary of rabbit.
