Research and progress of the preparation technologies of polyferric sulphate

聚合硫酸铁是一种新型的无机高分子絮凝剂,具有很强的除浊、脱色、去除有机污染物及重金属的能力,近年来在水处理中得到了广泛的应用。介绍了聚合硫酸铁絮凝剂的制备方法,按不同的生产原料归纳了聚合硫酸铁的制备技术,分析了各种制备技术的特点,对各种制备方法进行比较,得出比较理想的制备方法,同时提出了改性聚合硫酸铁的制备方法,并对聚合硫酸铁研究的发展前景与研究重点进行了展望。

Polyferric sulphate （PFS）, as a new kind of highly efficient inorganic polymer flocculants, has strong capacities of turbidity removal, decolorization, and the removal of organic pollutants and heavy metal. In recent years it has been widely applied to water treatment. The preparation of PFS is introduced, the preparation technology of PFS made from different raw materials are summarized, their characteristics are analyzed and compared, the optimum preparation method of PFS is given. And, at the same time, the development foreground and research empha- sis of modified PFS are looked ahead.
