二元及三元离子交换体系的统计热力学

Statistical Thermodynamics of Binary and Ternary Ion Exchange Systems

本文用统计热力学方法对二元及三元离子交换体系进行了研究,得到了修正选择系数与交换剂组成关系的理论表达式,并得到二元交换体系的交换剂组分活度系数与组成的关系式,即Kielland公式.

The statistical thermodynamic treatment of ion exchange has been developed for binary and ternary systems in this paper. The relationships between the corrected selectivity coefficients and the compositions in exchanger phase have been derived for these systems, and the Kielland formula has been obtained for binary system.
