摘　　要：利用盐酸酸洗废液为原料来制备聚合氯化铁(PFC)。阐述了当前酸洗废液的来源和处理方法。经过氧化、水解和聚合得到聚合氯化铁。经检验,产品的p H(1%溶液)为2.4,亚铁含量≤1%,总铁(Fe2O3)15.4%,盐基度约12.3%。讨论了影响反应的相关因素和反应机理。Polymeric ferric chloride （PFC）was prepared from the hydrochloric acid pickling waste liquid in this study. The source and treatment method of pickling waste liquid were explored. PFC was synthesized by oxida- tion,hydrolysis and polymerization. The final products were measured to possess the following indexes ：the pH （1% solution）is about 2.4;the ferrous content is less than 1.0%, the ferric content（Iron（III） oxide） is 15.4%;the basicity is about 12.3%. The related factors and reaction mechanism of the reaction were discussed as well.
