英文摘要	应用Corning-价阳离子选择电极（M~＋－ISE）和Orion氯离子选择电极组成可逆电池，CI~－－ISE\|RbCl（m），H2O（1－x），DMF（x）M~+－ISE．测量该电池标准电动势E_m，运用扩展的Debye－Hckel公式，计算RbCl在283．15至318．15K七个温度下由H2O至H2O－DMF混和溶剂的标准迁移自由能ΔG和在不同组成（H2O－DMF）混合溶剂中平均离子活度系数γ±，并对迁移自由能及活度系数随混合溶剂有机物组份的摩尔分数的变化进行了讨论。; The reversible cell used in this work consists of the monovalent cation selective electrode and chloride selective electrode, namely Cl--ISE \ RbCl(m), H2O(1 - x), DMF(x) \ M+ - ISE The standard electromotive forces of the above cells have been measured at seven temperatures ranging from 283.15 to 318.15 K, and the standard free energies of transfer Delta G(t)(theta) of RbCl from H2O to H2O-DMF mixed solvents, mean ionic activity coefficients gamma(+/-) of RbCl in mixed solvents and its medium effects have been calculated. The behavior of Delta G(t)(theta) and gamma(+/-) of RbCl with mole fractions x of DMF in the mixed solvents have been discussed.; SCI(E); 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 1; 08; 691-697; 14
