阳极溶出催化伏安法的理论研究 Ⅱ.不可逆电极溶出

Theory of Anodic Stripping-Catalysis Voltammetry Ⅱ.Stripping Process at an Irreversible Electrode

本文对在玻璃碳电极上不可逆溶出催化的理论进行了研究,推导了溶出催化过程的电流方程,峰电流和峰电势方程,并用微计算机模拟出各种关系曲线,从理论方程得知溶出催化伏安法所得的峰电流比溶出伏安法的峰电流提高了二个数量级。本文还用钯的溶出催化实验验证理论方程,所得的实验结果均与理论方程相吻合。

The theory of stripping-catalysis voltammetry(SCV)for an irreversible electrode process on a glassy carbon electrode was systematically studied. The theoretical equations of SCV for an irreversible electrode process have been derived. The experiment with Pd°stripping catalysis system of SnCl_2-HCl-HC1O_4 was employed to verify the theoretical equations. The theoretical conclusions were in good agreement with the experimental data.
