Abstract

The electrochemical properties of cobalt(II), nickel(II), and iron(II) ions are studied by cyclic voltammetry in the presence of increasing amounts of 2,2'-bipyridine (bpy). It is shown that the addition of insignificant amounts of bpy (10–50 mol %) to solutions containing cobalt(II), nickel(II), and iron(II) ions leads to stabilization of the reduced metal(0) forms and prevents both their electrochemical deposition and the formation of unsoluble metal associates.

2,2'-联吡啶存在下钴（II），镍（II）和铁（II）离子的电化学性质

摘要

在增加的2,2'-联吡啶（bpy）存在下，通过循环伏安法研究了钴（II​​），镍（II）和铁（II）离子的电化学性质。结果表明，向含有钴（II），镍（II）和铁（II）离子的溶液中加入少量的bpy（10-50 mol％）可以稳定还原的金属（0）形式并防止它们的电化学沉积和不溶金属缔合物的形成。
