摘　　要：向聚硅酸中加入铝盐、铁盐、硼砂制得含硼聚硅酸金属盐复合絮凝剂,用电子显微镜观察分析硼加入对絮凝剂形貌的影响,通过红外光谱分析研究各成分间的相互作用,并考察溶液的电学特征。结果表明:硼加入不会改变复合絮凝剂自身形貌,但能使聚集体长度加长、聚合度增大、结构更致密;适量硼的加入虽未改变硅酸的自聚和Al3+,Fe3+的水解聚合反应,但却以某种形式和聚硅酸及铝铁的多核羟基络合物发生反应,使得溶液的电学特征产生了一定的变化。pared by dition on teraction A series of po introducing alu the images and between the co lysilicate-containing boron composite inorganic polymer flocculants are preminum salt, ferric salt and borax into polysilicic acid. The effect of boron adstructure mposltlOn ges of flocculants are not basically changed when boron is added, but the polymers have become larger with more impact structure, the aggregates have larger and longer branches and denser ramifications. Though the boron addition has not changed the hydrolysis polymerization of Al^3＋, Fe^3＋ and self-polymerization of silicic acid, it has reacted with the polynuclear hydroxy complexes of Al^3＋, Fe^3＋ and polysilicic acid in a certain way and changed the electrical conductivity of the solution.
