如何提高絮凝剂的电中和能力，一直是水处理领域探求的热点之一。本文是在铝铁共聚合的基础上引入Ｓｎ４＋，以提高共聚物所带电荷量，并通过水解聚合过程中的电位滴定及试样的扫描电镜像，对其共聚作用的化学特征及晶形貌象做了初步探讨。为深入研究铝铁锡无机高分子絮凝剂提供了必要的实验依据 How to improve the electric neutralization capacity of flocculant has been one of the hot spots explored in the field of water treatment. In this paper, Sn4 + was introduced on the basis of Fe-Fe copolymerization to increase the charge amount of the copolymer. Through the titration of potentiometric titration and scanning electron microscopy (SEM) of the sample, the chemical character and crystal morphology Like to do a preliminary discussion. It provides the necessary experimental basis for in-depth study of inorganic iron-tin-iron polymer flocculant
