摘要： 本文报道求取if～E曲线的一种双电解池差分装置。通过扣除交流示波极谱法总电流中双电层充电电流ic,测量法拉第电流对工作电极电位的曲线(即it～E曲线),可提高灵敏度。

Abstract: To improve the sensitivity of cyclic derivative chronopotentiometry, the instrument is constructed by using two electrolytic cells, the measuring cell and the blank cell, to cancel most of the charging current of the electrical double layer. if-Ecurve is obtained and used in analysis in place of dE/dt-Ecurve.

Key words: Cyclic derivative chronopotentiometry, if-E curve, Differiential instrument, Twin elec-trolytic cells
