磺基水杨酸铁配合物的薄层光谱电化学研究

Study of the Spectro-electro Chemistry of Fe￣(3+)-Ssal/Fe￣(2+)-Ssal

本文采用自制的长光程薄层光谱电化学他，研究了磺基水杨酸铁配合物的吸收光谱的电化学特性，获得了不同电位下的薄层吸收光谱，测定了磺基水杨酸铁配合物的克式量电位Ｅ°及反应得失电子数ｎ，同时，用循环伏安法（ＣＶ）测定了在不同的ｐＨ值下，体系的峰值电位，与光谱电化学法相比较，得到较满意的结果．

The spectro-electro chemistry characteristics of the complex compounds of Fe3+-Ssal/Fe2+-Ssal have been studied by using a long-light-path, thin-layer spectroelectro chemistry cell. Through the experiments, the different thin-layer absorption spectrums under different electric potentials have been obtained; the formed electric potential (E°)and the number of the electrons (n) transferred in the reaction have been determined.Furthermore,a comparison experiment has been made with the CV method. Its results are also satisfactory.
