摘　　要：以水玻璃、无机酸和氯化铁为原料制备了含铁聚硅酸（ＦＰＳ），对其制备过程中的若干影响因素进行了研究．结果表明：以活化时间为１ｈ、Ｆｅ／Ｓｉ比为１时，所制备的ＦＰＳ具有最佳混凝性能．同时对其混凝特性进行了初步研究，表明ＦＰＳ具有较宽的ｐＨ适用范围，并且形成絮体速度快、絮体结实粗大．与聚合铁进行混凝对比表明，ＦＰＳ具有更优的混凝除浊性能．A new kind of inorganic polymer flocculant——Ferric Polysilicate(FPS) was prepared by using water glass,ferric chloride and inorganic acid as material. Several factors of preparation were discussed. The experimental results showed that FPS was best prepared at Fe/Si ratio of 1 and activation time of one hour. Compared with PFC, FPS showed better capability of turbidity removal.
