摘要/Abstract

摘要： 本文提出了超微环电极上稳态伏安曲线理论,用K₄Fe(CN)₆·KCl体系和超微金环电极(T_i=25.7μm,T₂=20.2μm)对理论进行验证,测得的伏安曲线与理论相符。

关键词: 超微环电极, 稳态伏安曲线, 极限电流

Abstract: The present paper deals with the theory of steady-state voltammetric cure at a ultramicror-ing electrode.In order to examine the validity of the theory, experimental studies on the system of Fe(CN)₆^4- ions in 0.5 mol/L KCl solution were carried out at a ultramicro-gold-ring electrode(τ₁ = 25.7 μm, τ₂ = 20.2μm).The experimental voltammograms are in good agreement with the theoretical ones.

Key words: Ultramicroring electrode, The steady-state voltammetric curve, Limiting current
