摘要
本文试制了铜电极并对碘离子在铜电极上阴极溶出伏安法的各种条件进行了研究。分析了海生物中碘。用三角波循环伏安法观察了电极反应过程。
A method for preparation of copper electrode is reported, and the behaviour of iodine ion on rotatiny copper electrode model BDX is investigated by cathodic stripping voltammetry. Various factors(stripping curve of different base electrolyte, pre-treatment of electrode, pre-electrolysis potential and time, pH value, dependence of the concentration of iodine ion on the peak height etc.) were also investigated. This method has been used to determine iodine in sea orgnism samples. The electrode process by triangle cyclic voltammetry has also been investigated.
