摘　　要：研究了电解质非均相化现象对钨离子交换的影响。研究表明:WO42-和Cl-的非均相化差异导致WO42-正向吸附的工作交换容量降低,逆向吸附的工作交换容量提高;提高交前液WO42-浓度,增大树脂层高度,降低离子交换线速度可扩大正逆向吸附交换容量的差异。正向解吸速度降低可提高解吸液浓度、减少解吸剂的用量。This paper studies electrolyte heterogeneous phenomenon and its influence on tungsten ion exchange.It shows that the homogeneous change of WO42-and Cl-make WO42-positive adsorption of exchange capacity reduced,but reverse adsorption exchange capacity increased;Improve the WO42-solution concentration,increasing the resin layer height,and reducing the ion exchange speed,will strengthen the heterogeneous of features.Low-speed of the positive desorption can increase desorbing agent solution concentration and reduce the dosage of desorbing agent.
