摘要
利用轧钢酸洗废液制备出一种新型高效的无机高分子絮凝剂-聚合氯化铁,进行了合成条件研究。研究结果表明利用酸洗废液制备聚合氯化铁的反应条件:反应温度控制在常温,废液中二价铁与氧化剂氯酸钠的物质的量的比为1∶0.08,每100mL酸洗废液加入17 mL浓盐酸,反应时间在5 min。所制得的聚合氯化铁产品,总铁含量大于40%,盐基度为58.7%,密度为1.3g/mL。
One new inorganic poly ferric chloride was prepared from steel rolling acid waste in lab.. The results showed that the optimum synthetic conditions were： reaction temperature was controlled at room, mass proportion of Fe^2＋ in acid waste and oxidant NaClO3 was 1 ：0.08, volume of HC1 adding in 100 mL acid waste was 17 mL and reaction time was 5 rain. The total iron of the prepared PFC is bigger than 40%, the average basicity is 58. 7% and the density is 1.3 g/mL.
