释放螯合滴定法测定铊

Determination of Thallium by Chelatometry with Releasing Agent

本文提出以盐酸氨基脲作释放剂 ,选择性螯合滴定法测定铅铊合金、铊化物和硫酸铊中的铊含量。实验结果表明 ,常见金属离子都不干扰测定铊。

The thallium content in Al Tl alloys,thallides and thallium sulfate are selectively determined by chelato metry with aminourea hydrochloride used as the reasling agent.It is experimentally shown that none of the common metal ions will interfere in the determination of thallium.
