摘　　要：采用大孔弱碱性树脂在弱酸性条件下吸附仲钨酸铵结晶母液中的钨 ,同时除去大部分C1-,用NaOH进行解吸 ,所得Na2WO4 返回主工艺流程。该法简单可行 。The process of big-hole weak alkaline resin applied in adsorbing tungsten from APT crystalline mother liquor in the weak acid is presented.In this process of removing most Cl- by the adsorbing of NaOH,gained Na2WO4 is applied in main process again .The method is economic and feasible on its simplicity and rationality.
