【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)离子形成络合物的极谱行为,发现在中性或微硷性的溶液中铊更多还原

【Abstract】 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% Na₂SO₃ 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.更多还原
