用硫酸根来增聚聚羟基氯化铝是提高絮凝效率的一种有效方法,但对于硫酸根的加量多少最合适,目前尚无定论。本文以钠型黑山白土为标准样品。用两种测定方法以及测定增聚羟基氯化铝(PACS)的分子量来论证以Al~(+++)/SO_4~==8为最好。同时指出提高增聚聚羟基氯化铝的碱化度虽能提高絮凝效率,但降低了稳定性。
Sulfate to poly poly aluminum chloride is an effective way to improve the flocculation efficiency, but for the amount of sulfate most appropriate, it is not conclusive. In this paper, sodium type Montenegro clay as a standard sample. The best determination of Al ~ (+++) / SO_4 ~ == 8 is demonstrated by the two methods of determination and the determination of the molecular weight of poly-aluminum hydroxychloride (PACS). At the same time, it is pointed out that increasing the degree of alkalization of poly-aluminum poly-aluminum chloride can improve the flocculation efficiency but reduce the stability.
