摘要
采用扩展的Debye-H(?)ckel方程来表示溶剂化离子的活度系数,并应用数学处理消去渗透系数(?),从而建立了一个只与溶剂化数h有关的单参数活度系数公式.经对48个体系的处理,表明本文所建立的单参数活度系数公式具有良好的适用性.
In this paper the extended Debye-Huckel formula is used to represent the activity coefficient of solvated ions, and osmotic coefficient ? in the formula is cancelled by mathematical treatment. So a new formula for electrolytic activity coefficient, which contains only a single parameter h, is established. In order to test the reliability and practicability of the new formula, the activity coefficients of 48 electolyte- containing systems reported in literature are calculated. The results show good accuracy. Generally, the mean relative deviation of every processed system is less than 0. 8%.
