摘要
介绍一种简易的光谱电化学电池,它采用双铂片工作电极,具有光程长、灵敏度高等特点.采用该电池对邻一联甲苯胺和铁氰化钾两体系进行了光谱电化学(E°′和n值)测量,结果表明;??曲线线性较好.相关系数分别为0.9988和0.9996E°′的变动系数均小于1%.
A Simple Spectroelectrochemical cell has been designed. Two platinum plates are used as working electrodes. The cell features long pathlength and high sensitivity. We had measured E°′ and n values of o-tolidine and potassium ferricyanide using this cell. The experimental results show that the linearity of E-log? is good, correlation coefficients are 0.9988 and 0.9996 respectirely, and the variation coefficients are less than 1%.
