Additive Cyclic Square Wave Voltammetry For Adsorptive-Complex Irreversible System——Ⅰ. Controlled by the rate of complexing reaction

推导出受前行化学反应控制的络合吸附不可逆体系叠式循环方波伏安法的电流方程及其各阶导数卷积方程,研究了各峰电流与诸因素的关系,并推导出峰电势表达式。理论推导与实验结果一致。

In this paper, a theoretical treatment of additive cyclic square wave voltammetry is givenfor adsorptive-complex irreversible system (controlled by the rate of complexing reaction). Thevarious relations of convolute and derivative peak currents to related parameters is investigatedsystematically. The peak potential equation is also given. Experiments with Zn(Ⅱ)-zincon complexwere carried out to verify the theory. The results agree with the theoretical conclusions.
