【摘要】 <正> 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-硫代甲酰胺与铊(Ⅰ)离子形成络合物的更多还原

【Abstract】 In the presence of cupron, there exists a sensitive adsorptive complex waveof the complex formed by thallium ions. The most suitable supporting electro-lyte solution is composed of 0.05M-KBr, 0.4% Na₂SO₃ and 2.10^-4 M-cupron. Thewave is available for the determination of 0.1--25 ppm T1. The wave peakappears at --0.8V.更多还原
