摘　　要：本文用流通池介质交换差示脉冲阳极溶出伏安法在盐酸介质中富集,而以碳酸钠-碳酸氢钠缓冲溶液为溶出介质,有效地分离了酸性介质中Cu(Ⅱ)、Sb(Ⅲ)、Pb(Ⅱ)、Tl(Ⅰ)、Cd(Ⅱ)、In(Ⅲ)的重叠溶出峰,实现了多离子的同时测定。Using a home-made flow-through cell,the separation of overlapping peaks for copper(Ⅱ) ,antimo-ny(Ⅲ),lead(Ⅱ ), thallium(Ⅰ), cadmium(Ⅱ), indium(Ⅲ)in acidic media by means of medium exchange is investigated and simultaneous determination of multielement is realized.
