摘要
氯酚类化合物属于优先控制污染物。采用水热法合成了Cu O、Fe_3O_4及Cu O-Fe_3O_4复合材料,用于催化Oxone降解4-氯酚。研究了Cu O、Fe_3O_4及Cu O-Fe_3O_4复合材料催化Oxone降解4-氯酚的效能及影响因素,结果表明,CuO和Fe_3O_4进行复合后催化Oxone降解4-氯酚的反应效率及反应速率均得到显著的提高,且Cu O-Fe_3O_4复合材料的投加量低于Cu O、Fe_3O_4单独催化Oxone时的投加量,并且降解效果更佳。
Chlorophenols belong to priority control pollutants.CuO,Fe_3O_4 and Cu O-Fe_3O_(4 )composites were synthesized by hydrothermal method to catalyze the degradation of 4-chlorophenol by oxone.The effect of CuO,Fe_3O_4and CuO-Fe_3O_4 composite materials on the degradation of 4-chlorophenol by oxone was studied.The results showed that the reaction efficiency and reaction rate of 4-chlorophenol degradation by oxone over CuO and Fe_3O_4 composite materials were significantly improved,and the dosage of CuO-Fe_3O_4 composite materials was lower than that of CuO and Fe_3O_4 alone,and the degradation effect was better.
