以赤铁矿为主要原料，用硫酸提取Al3+、Fe3+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。

이적철광위주요원료，용류산제취Al3+、Fe3+제비료취합류산려철（PAFS）。산품채용XRD급TEM진행표정，병이황하수위원수진행서응실험연구。결과현시，자제PAFS적서응성능우우시수취려（PAC），당기투가량위12 mg/L、pH재5.0～8.5시，COD거제솔、탁도거제솔분별체도40%、99%이상。
The polymeric aluminum ferric sulphate (PAFS) has been prepared by using hematite as main raw material and extracting Al3+and Fe3+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.
