Investigations on Polarography with Linearly Changing Potential ⅩⅢ. On the General Theory for the Adsorptive-Coraplex Wave

本文讨论包括吸附、扩散、电极反应速率等多种因素同时发生作用时配位吸附波的理论,提出的统一方程式包括可逆、不可逆和准可逆过程常规示波极谱、一次导数和二次导数极谱波方程式.利用铅(Ⅱ)-8-羟基喹啉体系进行验证,理论与实验结果相符.

It is discussed that the theory of adsorptive-complex wave for the electrode process controlled simultaneously by multiple factors such as adsorption, diffusion, charge transfer rate and so on. The general equations for the reversible, quasi-reversible, irreversible adsorptive-complex waves include normal polarographic wave equation, the first derivative polarographic wave equation and the second derivative polarographic wave equation is also investigated. The theoretical conclusions are in good agreement with experimental data for the reduction of Pb(Ⅱ) in the presence of oxine.
