摘要
碳纤维电极已引起越来越多人们的注意,其在电分析中的应用已有综述。近年来国外关于碳纤维电极制备和性质已有许多报道,国内尚未见到报道。本文介绍一种简易制法,并对其电化学行为进行了某些探讨。实验结果表明,由于处理方便,性能良好,可用于阳极溶出伏安法测定饮用水和纯盐中某些重金属元素。
Carbon fibers were used as the support for a mercury film electrode in anodic stripping voltammetry.The procedure for making mercury film carbon fibers electrode is simple and easy. The effects of deposition potential, deposition time, scan rate and supporting electrolyte were discussed. The linear response was given for Pb and Cd. The limit of detection was 0.2ppb for Pb. The mercury film carbon fibers electrode was used for determining Pb and Cd in KCI(GR) and tap water.
