摘要
本文研究了油/水界面电解的示差半微分和常规循环伏安行为,实验证明采用示差技术后,残余电流基本消除,“电位窗”平台向左右拓宽约50mV,离子在W/nb界面传递的伏安特性与普通半微分和常规循环伏安法相似,但峰形改善,检测限降低约1个数量级。
Differential semidifferential cyclic voltammetry (DSCV) and Differential cyclic voltammetry (DCV) for the electrolysis at the oil/water interface have been studied. It was showed that the residual current was almost eliminated so that both sides of the platform in 'potential window' have been expanded as about 50mv when using differential technique. The Characteristics of DSCV and DCV waves for the transfer of ions at the w/nb interface were similar to those of semi-differential and normal cyclic voltammetry, however the peak shape was wimproved and the limit detection decreased about 1 order.
