英文摘要	以电化学活化玻碳为基底电极原位制备金属铋膜电极,用之于分析Pb2+、Cd2+.方法如下:在氢氧化钠溶液中,由恒电位或循环扫描电位方法活化玻碳电极,随后以稀盐酸替代传统的醋酸缓冲液作为分析溶液将Bi3+与Pb2+、Cd2+共沉积在活化玻碳电极表面,再以方波阳极溶出分析法(SWASV)检测金属离子.结果表明:经简单的电化学清洗步骤即可高重现地再生电极表面,大幅度提高检测Pb2+、Cd2+的灵敏度,检测范围也可拓展至高卤素离子含量的样品.; The application of electrochemically activated glassy carbon ( GC) in the in-situ preparing of bismuth film electrodes ( BiFEs) to analyze Pb2 + and Cd2 + was investigated. The glassy carbon electrodes were electrochemically activated by either potentiostic or cyclic polarization in 1 mol·L-1 NaOH solution. Experimental results show that employment of HCl solution as the analytical solution not only can reproducibly renew the electrochemically activated GC electrode surface with an electrochemical clear procedure,but also can greatly enhance the sensitivity of BiFes method for analysis of Pb2 + and Cd2 + . The test range thus was extended to the sample containing high chloride anion concentration.; 作者联系地址：厦门大学化学化工学院化学系;; Author's Address: Department of Chemistry,College of Chemistry and Chemical Engineering,Xiamen University, Xiamen 361005,Fujian,China
