研究了粒度不均一离子交换剂与水溶液中离子之间,在粒内扩散和液膜扩散联合控制反应速度时的同位素交换反应动力学;导出了在各种不同半径交换剂上的交换度的解析表达式,并用电子数字计算机进行数值计算。前人及文献[5]所得的解析表达式,可纳入本文所导出的表达式。
The kinetics of isotopic exchange reaction between inhomogeneous ion exchangers and ions in aqueous solution was studied. The kinetics of isotope exchange reaction was investigated when the intra- and inter-particle diffusion and liquid-membrane diffusion were combined to control the reaction rate. The exchange degree of different radius exchangers Expressions, and numerical calculations using electronic digital computers. The analytic expressions obtained by predecessors and literature [5] can be included in the expressions derived from this article.
