摘要
针对离子交换法生产ＡＰＴ现行工艺中结晶母液必须另设辅助流程处理的缺点，提出了一种新的工艺流程：用电渗析法从结晶母液中选择性地脱除氯离子，避免了氯的积累，处理后的结晶母液可直接返回主流程。
A new method for recovering the tungsten from the crystallized barren liquor is studied.In this process，the chloride ion can be renioved selectively from the barren liquor by usingelectrodialysis method．Then the possible industry application of this process is discussed.
