【摘要】 <正> 吸附溶出伏安法和新极谱法是近年发展起来的两种新型电分析方法。作者将二者有机结合,应用1.5次和2.5次微分新极谱法在悬汞电极上研究了镉碘络合物吸附体系。关于铅碘络合物极谱吸附波的研究已有文献报道,其检测下限均在ppb级以上。本文应用悬汞电极—吸附溶出新极谱法研究了铅碘络合物吸附体系和各项测量参数。在乳酸(0.8％)-碘化钾(0.04M)-四丁基碘化铵(0.016％)体系中(pH2.6),在-0.52V(vs.SCE)处有一更多还原

【Abstract】 The better supporting electrolyte for the titled method to determine microamount lead is achieved and the behaviour of the adsorptive wave is studied.It can be used to determine lead over 0.4—100 ppb in water, and urine et al. This method is rapid, simple, sensitive and accurate.更多还原
