摘要
本文使用恒电位方波慢扫描法，测量了不同浓度的２，２＇─联吡啶在金电极表面的微分电容曲线，从而得到２，２＇─联吡啶在金电极表面的吸附电位范围为＋０．６５～－１．２０Ｖ（ＶＳ．ＳＣＥ）、吸附类型服从Ｆｒｕｍｋｉｎ型吸附、吸附自由能为－３５．８６ＫＪ·ｍｏｌ－１。
The adsorption behaviour of 2,2'-bipyridine at a gold electrode was studied by potentiostatic square wave slow sweep methods. The differential capacity curves were measured for 2,2'-bipyidine solution of different concentrations at a gold electrode. Experimental results indicated that the adsorption of 2,2'-bipyridine at a gold electrode are in the potential range from +0.65V to ─1.20V(VS.SCE).The Frumkin isotherm for adsorption was obeyed.The free energy of adsorption was obtained for △G=-35.87KJ·mol-1.
