摘　　要：向聚硅酸中引入铝盐、镁盐、锌盐制得聚硅酸金属盐复合絮凝剂(PAZMSc),用红外光谱研究了各成分间的相互作用,并对其絮凝性能进行了考察。红外光谱证实了PAZMSc中部分铝离子、锌离子、镁离子及水解络合离子可与共存的聚硅酸起螯合反应生成铝锌镁硅聚合物,其絮凝性能高于聚硫酸铝。Polysilicate-aluminum Zincemagnesium（PAZMSc） was received by adding aluminumsal salt、Zincesaltand magnesium salt into polysilicate acid.The interaction among all components was observed by infrared spectrum,so the flocculation can be investigated.The in-frared spectrums proved that Al3＋、Mg2＋、Zn2＋,hydroxyl ion and poly-silicicacidion can be chelated and maded into new polymer PAZMSc.The coagulation property of PAZMSc is better than PAS.
