摘要
以钛白粉生产废料作为原料制得了聚合硫酸铁。在常温下采用氯酸钠溶液滴加于硫酸亚铁的硫酸溶液中可使氧化还原反应完全。Fe^2＋含量得到控制。控制[SO4^2-]／[Fe]〈1．5.1％PFS溶液pH值在2～3不产生Fe（OH）3沉淀。
Polymeric ferric sulfate was synthesized by direct oxidation using the sodium chlorate in normal temperature and normal pressure, it is discussed that the effects of various factors such as oxidant,sulfuric aicd,technological conditions in reaction on product properties.
