处理仲钨酸铵结晶母液的研究

Study on the treatment of ammonium paratungstate mother liquor

针对离子交换法生产仲钨酸铵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 ,用纳滤法从结晶母液中选择性地脱除氯离子 ,避免了氯的积累 。

A new method for recovering the tungsten from the crystallized mother liquor is studied,in this process,the chloride ion can be removed selectively from the mother liquor by using nanofiltration method.The industry application of this process is discussed.
