以ＡｌＣｌ３·６Ｈ２Ｏ、ＮａＯＨ、盐酸和水玻璃为原料制备了不同碱化度（Ｂ）及不同Ｓｉ／Ａｌ摩尔比的系列聚硅氯化铝混凝剂（ＰＡＳＣ），采用Ａｌ－Ｆｅｒｒｏｎ逐时络合比色法和微电泳技术研究了ＰＡＳＣ中铝的水解产物形态分布及铝的水解沉淀物的带电特性，考察了Ｂ及Ｓｉ／Ａｌ摩尔比对ＰＡＳＣ中铝水解产物形态分布及带电特性的影响情况，并与聚合氯化铝（ＰＡＣ）进行了比较．实验结果表明，Ｂ对ＰＡＳＣ的形态分布有较大影响．Ｓｉ／Ａｌ摩尔比对ＰＡＳＣ的形态分布有一定的影响；Ｂ和Ｓｉ／Ａｌ摩尔比影响ＰＡＳＣ水解沉淀物的带电特性，随Ｂ升高及Ｓｉ／Ａｌ摩尔比增大，ＰＡＳＣ的零电位向低ｐＨ方向移动．
A series of polysilicon aluminum chloride coagulants (PASCs) with different degree of basicization (B) and different Si / Al molar ratios were prepared by using AlCl3 · 6H2O, NaOH, hydrochloric acid and water glass as raw materials. Colorimetric method and microelectrophoresis technique were used to study the morphology distribution of aluminum hydrolysates in PASC and the electrification characteristics of aluminum hydrolysates. The effects of B and Si / Al mole ratios on the morphologies and charge characteristics of aluminum hydrolysates in PASC were investigated. The situation was compared with polyaluminum chloride (PAC). The experimental results show that B has a great influence on the morphological distribution of PASC. The molar ratio of Si / Al has a certain influence on the morphology distribution of PASC. The molar ratio of B to Si / Al affects the charging characteristics of PASC. With the increase of B and the increase of Si / Al molar ratio, pH direction.
