摘要
本文提出了在醋酸－醋酸钠－酒石酸钾钠介质中连续测定天然水中铋、铜、铅、镉、锌、锰的微分阳极溶出伏安法。研究了底液的组成和波峰的性质，试验了共存元素的允许量。方法灵敏度高，不经分离富集，可直接用于测定天然水中上述六种离子。
This paper suggests the differential anodic stripping voltammetry in acetic-acid,sodium acetate and potassium sodium tartrate mediums in simultaneous determination of Bi, Cu,Pb,Cd,Zn and Mn in natural water.The constituents of the supportiong electrolyte and nature ofthe wave peaks are studied.Allowable amount of coexisting elements is tested.The method has ahigh sensitivity and can be be applied directly to the determination of the above-mentioned sixions in natural water without separation and concentration.
