本文报导一种灵敏的测定痕量铬的吸附催化溶出伏安法．在悬汞电极表面，铬一铜铁试剂络合物基于吸附原理被吸附富集，然后在氧化催化剂溴化钠存在下反向扫描溶出，其溶出峰电流与铬浓度分别在０．１０～０．８０和１．０～１５ｎｇ／ｍｌ范围内呈良好的线性关系．将该方法用于血清中痕量铬的分析，标准加入回收率在９７．０％～１０１．８％之间．利用多种电化学手段结合表面电化学理论，对电极过程机理进行了研究，提出可能的电极反应机理．
This paper reports a sensitive catalytic stripping voltammetric method for the determination of trace chromium. On the hanging mercury electrode surface, the chromium-copper-iron reagent complex is adsorbed and enriched based on the adsorption principle, then is reversely scanned and eluted in the presence of an oxidation catalyst sodium bromide, and the peak current and concentration of chromium are 0.10-0.0 .80 and 1.0 ~ 15ng / ml showed a good linear relationship. The method was applied to the determination of trace chromium in serum. The standard recoveries were between 97.0% and 101.8%. Using a variety of electrochemical methods combined with surface electrochemical theory, the electrode process mechanism was studied, and possible electrode reaction mechanism was proposed.
