| 摘 要： | 聚合氯化铝（ＰＡＣ）是一种应用很广的无机高分子絮凝剂。就目前国内外对聚合氯化铝的研究状况，重点介绍了其形态分布及研究方法，水解—聚合机理、絮凝机理，各形态组分的结构以及表征其性质的参数，提出了Ａｌ３＋在水解过程中通过Ａｌ１３及六元环形成三维骨架结构及层状结构的聚合模式，并对ＰＡＣ今后应该着重研究的方向发表了看法。

| Abstract: | Polyaluminium chloride (PAC) is a widely used inorganic polymer of coagulation in water treatment. This paper introduces the status of the study on PAC at home and abroad, hydrolysis polymerization mechanism, coagulation mechanism, the structure of each species and the propety parameters of PAC. This paper also advances a polymerization model of the formation of 3 dimension framework strucrure and layer structure form Al 3 cation through the stage of Al 13 polymer and hexamers. And the authors also offer their views about the leading research direction in the future. |
