摘要
本文对铜(Ⅱ)-腺嘌呤配位吸附波的极谱行为进行了研究。结果表明,当腺嘌呤浓度大于铜的浓度时,极谱波呈现为两电子还原配位吸附不可逆波。测定了配合物的组成及条件生成常数,对电极反应机制也进行了探讨。
In this paper the polarographic behavior of Cu (Ⅱ)-adenine adsorptive complex wave has been studied in 0. 1 mol/L IIAc-NaAc medium. The experimental results show that when Cade 》CCu(Ⅱ), polarographic waves are irreversible ones involving two electron-reduction. The composition, stability constant and diffusion coefficient of the complex are determined. The mechanism of electrode process has also been discussed.
