双铂片光谱电化学电解池的研制及铁的分析

Design of a Spectroelectrochemistry Cell with Double Platinum Plate Electrodes and the Analysis of Iron

自行设计、研制了一种适合于光谱电化学定量分析的双铂片长光程电解池，并对铁－邻菲啉体系进行了测定，确定了测定微量铁的最佳实验条件：ＮａＡｃ浓度０．１ｍｏｌＬ￣（－１），邻菲啉浓度６ｘ１０￣（－３）％，电解电压为１．６Ｖ。工作曲线线性良好，Ａ＿（ｍａｘ）—Ｃ和Ｋ－Ｃ曲线相关系数分别为０．９９９６和０．９９９７。

An electrolvtic cell of double platinum plate electrodes is designed for the quantitative anal-ysis of spectroelectrochemistry.The micro-iron ion is measured under certain conditions.The lineari-ty of the working curves are good with the correlation coefficients.
