摘　　要：文章研究了聚吡咯膜对汞离子的配位富集作用,并用循环伏安法加以证实。在0.1～10mg·L-1的汞离子浓度范围内,汞离子浓度与还原电流成线性关系。该方法可用于废水中汞离子含量的检测。Coordination preconcentration of hydrargyrumby polypyrrole modified electrode was studied and verified b y using the meth-ods of cyclic voltammetry.The experimental results showed that cathodi c peak current was proportional to th e concentration of Hg 2+ in the range 0.1～10mg ·L -1 .This method could be used for the determination of Hg 2+ in pollution water.
