摘要
本文研究了玻碳汞膜电极计时电位港出法，方法可对溶液中1×10-10g／wL以上宽达4个数量级的Cu2+、Pb2+、Cd2+进行测定.发样测试相对标差小，回收率高.
The determination of Cu、Pb and Cd by chromopotentiometric stripping analysis had heen studied in this paper. The mercury membrane modified glasscarbon electrode was used in test.The linear range of the calibration curre is 1×10-10,～10-6g/mL
