摘要
为实现碳酸氢铵合成无定型羟基氧化铁材料的同时对副产物硫酸铵进行回收,针对硫酸铵中铁杂质的去除,对除杂过程中的影响因素作了较为系统的考察。笔者采用氧化沉淀分离法结合絮凝剂的使用,能够有效地除去硫酸铵中的铁杂质,除杂率达到100%。
To facilitate the simultaneous synthesis of no-crystal iron oxide hydroxide from ammonium bicarbonate and recovery of ammonium sulfate by-product, the factors affecting the purification of ammonium sulfate are studied. In this study, the efficient removal of iron impurity in ammonium sulfate can be achieved by combining the oxidationprecipitation separation method with employment of flocculants. The impurity removal rate can reach 100%.
