摘　　要：用赤铁矿尾矿矿粉和粉煤灰作为原料,合成不同Fe3+/Al 3+摩尔比的复合阳离子型聚合硫酸铝铁(PAFS).合成物平均分子量5.1×104,为无机高分子絮凝剂,红外光谱显示PAFS是兼有羟基桥联的铝铁共聚物.选取不同区段黄河水,将制得的PAFS与市售聚合氯化铝(PAC)进行对比实验,结果表明,在相同投药量下,PAFS的去浊率及COD去除率均高于市售PAC.Poly-alumino-iron sulphate（PAFS） with different Fe3＋/Al3＋ molar ratio were synthesized by hematite tailings slag and fly-ash.It is Inorganic Polymer Flocculant and average molecular weight is 5.1×104.IR spectra results showed that PAFS is the copolymer of hydroxyl-bridged iron and aluminum.Experiment water that was collected from different sections of Yellow River,the turbidity removal rate and COD removal rate of PAFS are better than the commercial PAC.
