摘　　要：以赤铁矿为主要原料，用硫酸提取Al^3＋、Fe^3＋制备了聚合硫酸铝铁（PAFS）。产品采用XRD及TEM进行表征，并以黄河水为原水进行絮凝实验研究。结果显示，自制PAFS的絮凝性能优于市售聚铝（PAC），当其投加量为12 mg/L、pH在5.0～8.5时，COD去除率、浊度去除率分别达到40%、99%以上。The polymeric aluminum ferric sulphate （PAFS） has been prepared by using hematite as main raw material and extracting Al^3＋and Fe^3＋from sulphuric acid. The product is characterized by X-Ray Diffraction（XRD）, and transmission electron microscopy （TEM）. The Yellow River water is used as raw water,and the flocculation experiment is conducted. The results show that the flocculation capability of home-made PAFS is superior to commercial poly-aluminum （PAC）. When its dosage is 12 mg/L,and pH 5.0-8.5,the COD removing rate and turbidity removing rate can reach above 40%,and 99%,respectively.
