Synthesis and application of polymeric ferric sulfate

LI Wei-ya

Abstract

The prepn.method of polymeric ferric sulfate was studied with FeSO4 as the raw material and KClO3 as the oxidant.The influence of the raw material input quantity,reaction temp.and time and pH parameters etc.on the FeSO4 oxidation and the polymeric ferric sulfate prepn.were studied.The technological conditions were optimized with orthogonal expts.The performance of polymeric ferric sulfate depended on the total iron content and the base degree.The product had stable quality,high base degree and good wastewater treatment effectiveness when prepd.with 20 g FeSO4,80 mL water 18 mL sulfuric acid,and 17 g KClO3,and reacted at 50~55 ℃.
