摘要
本文报道求取i_f～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i_c,测量法拉第电流对工作电极电位的曲线(即i_t～E曲线),可提高灵敏度。
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. it-E curve is obtained and used in analysis in place of dE/dt-E curve.
