摘要

引言随着水污染的加剧

水资源的再生利用已成为一个亟待解决的问题.混凝法是当前国内外众多水处理工艺技术中应用最为广泛的单元操作技术之一.而混凝效能的好坏主要取决于絮凝剂.因此高效絮凝剂的研究开发工作一直是水处理领域的热点.在六、七十年代

人们对聚合氯化铝(PAC)、聚合氯化铁(PFC)进行了较为深入的研究

并得到了广泛的应用.后来又在铁铝共聚合

尤其在加聚某些阴离子方面

作了新的探索.但目前尚未见到加聚Fe~(3+)、Al~(3+)以外的其他金属离子的研究报道。本文正是通过加聚sn~(4+)

即含有更高离子化合价的金属离子来提高絮凝剂压缩双电层和电中和能力

进而提高絮凝剂的凝聚性能

以提高水处理效果.

Abstract

How to increase the ability of charge neutrality of flocculant is one of the exploring hot points in water treatment. Adding Sn4+ in coplymeriting of Fe3+ to increse the charge of the copolymer was studied in this paper. The chemical characteristics and crystal image of the copolymer were also studied by potentiometric titration in copolymeriting and scanning electron micrograph. Essential experimental basis for further researching copolymerization of Fe( Ⅲ ) and Sn( Ⅳ) was put forward.
