本文用线性变势吸附伏安法研究了铌(Ⅴ)-酒石酸-2-(5′-溴-2′-吡啶偶氮)-5-二乙氨基苯酚三元配合物在汞电极上的电吸附性质,测定了表面浓度,讨论了吸附浓度的表达式及其与吸附时间、金属离子浓度、配位体浓度的关系。验证了吸附量与电极面积及还原峰电流的关系。证明了配合物在电极上的还原是一个可逆吸附的还原过程。
In this paper, the electrochemistry of linear voltammetry voltammetry was used to study the electrochemical behavior of niobium (V) -tartaric acid 2- (5’-bromo-2’-pyridylazo) -5-diethylaminophenol ternary complex on mercury electrode Adsorption properties, the surface concentration was measured, and the expression of adsorption concentration and its relationship with adsorption time, metal ion concentration and ligand concentration were discussed. The relationship between the adsorption capacity and the electrode area and the reduction peak current was verified. It is proved that the reduction of the complex on the electrode is a reversible adsorption reduction process.
