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
