利用Ni-Al合金粉的碱洗液制备聚合氯化铝

Preparation of aluminum polychloride by using the alkaline effluent from Ni-Al alloy powder washing

利用Ni-Al合金粉的碱洗液制备了聚合氯化铝 ,推导出盐酸添加量与产品中盐基度的关系 ,并用小试进行了验证。

Aluminum polychloride is prepared by using the alkaline effluent from Ni-Al alloy powder washing.The relationship between quantity of hydrochloric acid needed and concentration ratio of hydroxyl to aluminum is inferred,which has been proved by bench tests.
