摘　　要：本研究采用化学沉淀法制备磁性颗粒,并探索磁性颗粒对钢铁厂废水的吸附性能以及其再生再利用次数。探讨在不同pH值下、吸附时间及再生次数对磁性颗粒吸附含铁废水的影响,进行实验并确定最佳条件。实验结果显示在p H值7,吸附时间为8分钟时,磁性颗粒对于钢铁厂废水中铁离子的去除率可达到99%以上,磁性颗粒循环再利用次数可达8次。Magnetic particles were made by chemical precipitation method to explore the adsorption performance of magnetic particles for iron and steel plant wastewater.In this study,the effects of different pH value,adsorption and regeneration times on the adsorption of iron containing wastewater by magnetic particles were studied and the optimal conditions were determined.This study examined reusability of the magnetic particles could be reused up to eight times.
