摘要
应用一价阳离子选择电极和氯离子选择电极组成可逆电池.通过测定电池的电动势,根据溶液热力学原理,引用扩展的Debye-Hückel公式,计算求得了RbCl在(H2O~DMF)混合溶剂中的活度系数,一级、二级和总介质效应.并对RbCl的介质效应进行了讨论.
The reversible cells consist of the corning monovalent cation selective electrode (M +-ISE) and choloride selective (Cl --ISE) electrode,namely,Cl --ISERbCl( Q ) H 2O(1- x ),DMF( x )M +-ISE.The electramotive forces (-EmV) of measured cells have been determined at 298 15 K, then the activity coefficients and medium effects ( PME、SME、 Total) of RbCl have been calculated and discussed on the basis of solvation theory of electrolyte solution.
