摘　　要：本文提出了一种包含树脂相饱和因数的新型离子交换动力学表达式。该表达式以交换反应级数与饱和级数为表征。在不同交换反应体系和接触模式下对模型进行了验证,得出了相应的动力学表达式。模型与实验结果能较好地符合。An ion-exchange kinetics model including resin phase saturation factor is presented in this paper. The equation is characterized by the reaction order and the apparent order of saturation process. The e-quation was checked with different ion-exchange reaction systems and different contact methods. The corresponding kinetics equations were obtained. The kinetics equations better agreed with the experiment results.
