摘　　要：利用稀土铈(Ce)、硫酸亚铁和活性炭(AC)制备了Ce-Fe-AC复合材料,并利用该材料的铁碳微电解和类芬顿作用实现对阳离子蓝X-GRL的降解。当Fe/AC质量比为2∶1,Ce质量分数为10%,制备溶液pH为9时,得到的复合材料性能最优。投加2.0 g/L的Ce-Fe-AC复合材料对初始质量浓度为20 mg/L、初始pH为3的阳离子蓝X-GRL进行降解时,降解效果最好。且在染液初始pH为7、9的条件下,Ce-Fe-AC复合材料仍然具有较好的降解能力。Rare earth cerium(Ce),ferrous sulfate and activated carbon(AC)are used to prepare Ce-Fe-AC com⁃posite material.The iron-carbon micro-electrolysis and Fenton-like effect of the material are used to degrada⁃tion of Cationic Blue X-GRL.When m(Fe)∶m(AC)is 2∶1,w(Ce)is 10%,pH of the prepared solution is 9,the per⁃formance of the prepared composite material is good.When adding 2.0 g/L Ce-Fe-AC composite material to the degradation of Cationic Blue X-GRL with an initial mass concentration of 20 mg/L and an initial pH of 3,the degradation result is the best.It has good degradation ability under the conditions of initial pH of 7 and 9.
