A New Method of Peparing Polyaluminum Hydroxychloride From Kaolin-the Study of the Optimum Condition For the Process of Adjusting Basicity Wity Activated Kaoljn

本文提出了一种从高岭土制聚羟基氯化铝的新方法,并且研究了用活化高岭土作为盐基度调整剂的反应过程中,酸浸液浓度和盐基度、温度、时间等因素对调整过程的影响。

A new method of preparing polyaluminium hydroxychloride from kaolin was described. It studied the affection of the factors, such as the aluminium (III) ion concentration, the basicity before being adjusted,tempera-ture and time, on 'improving the basicity of sulution in the adjustment process. And the optimum condition for the process of adjusting basicity with activated kaolin was found.
