摘要
有关铊与有机试剂络合物来提高极谱测定的灵敏度,至今尚未见报导。基于S^(=)离子比I^(-)离子在滴汞电板上的特性吸附更强,我们选择一些含巯基-SH的试剂进行试验,观察了胱氨酸,硫脲,铜试剂,吡咯烷-α一硫代甲酰胺与铊(I)离子形成络合物的极谱行为。
In the presence of cupron,there exists a sensitive adsorptive complex wave of the complex formed by thallium ions.The most suitable supporting electrolyte solution is composed of 0.05M-KBr,0.4%Na_(2)SO_(3) and 2-10^(-4) M-cupron.The wave is available for the determination of 0.1-25 ppm Tl.The wave peak appears at-0.8V.
