摘　　要：应用Ｃｏｒｎｉｎｇ一价阳离子选择性电极（Ｍ＋－ＩＳＥ）和固态氯离子选择性电极（Ｃｌ－－ＩＳＥ）组成可逆电池，通过测定电池的标准电动势（Ｅｏｍ）求得了ＲｂＣｌ由Ｈ２Ｏ至（Ｈ２Ｏ－ＭｅＯＨ）和（Ｈ２Ｏ－ＤＭＦ）混合溶剂的标准迁移自由能（ΔＧｏｔ），并对ΔＧｏｔ的某些变化规律进行了初步的讨论．The reversible cells consists of the Corning monovalent cation selective electrode(M+-ISE)and choloride selective(Cl--ISE) electrode,namely The Standard Electromotive forces (E°m/mV)of the measured cells have been measured at 298.15k ,then the standard free energies of transfer (ΔG°t/kj·mo-1)of RbCl from H2O to (H2O-MeOH) and (H2O-DMF) mixtures have been calculated.The behavior of change of standard free energies of transfer of RbCl have been discussed on the basis of salvation theory of electrolyte solution.
