In order to explore the adsorption properties of red mud adsorbent for copper ion,red mud ad-sorbent had been prepared by granulating-calcinations with red mud as raw materials. Several influencing factors of copper ion removal performance have been studied,such as adsorption time,calcinations temper-ature,calcinations time,pH value and dosing quantity,and so on. The results showed that the adsorbent prepared by red mud with granulating-calcinations method has good removal performance for copper ions, and the concentration of copper ion could be reduced from 64. 00 mg/L to 0. 22 mg/L,and adsorbent ca-pacity could reach 1. 595 mg/g,the removal rate could reach more than 98%.%以赤泥为原料，通过造粒、焙烧的方法制备赤泥吸附剂，探讨赤泥吸附剂对铜离子的吸附性能。研究了吸附时间、焙烧温度、焙烧时间、pH值、吸附剂投入量等对赤泥吸附剂除铜性能的影响。结果表明，赤泥经过造粒、焙烧后制备的吸附剂对铜离子具有很好的去除效果，铜离子的浓度可以从64.00 mg/L降低到0.22 mg/L，吸附剂对铜的吸附容量可达1.595 mg/g，对铜离子的吸附率达98%以上。
