摘要

采用共沉淀法成功合成了磁性CoFe2O4/ZIF-9复合材料.以罗丹明B溶液为污染物模型,通过催化剂催化过一硫酸盐评价其催化活性.催化剂筛选结果表明,复合催化剂CoFe2O4与ZIF-9的摩尔比为1∶5为最佳配比.实验结果表明,在20 min内,用100 mg/L的PMS和50 mg/L的催化剂对罗丹明B的去除率为99.7％.CoFe2O4/ZIF-9复合材料具有制备简单、催化活性高、可重复使用、回收容易等优点,是修复水污染的高效催化剂.

Abstract

Magnetic CoFe2O4/ZIF-9 composites were successfully synthesized by co-precipitation method.The catalytic activity of CoFe2O4/ZIF-9 to peroxymonosulfate was evaluated with rhodamine B as model of contaminant.The results of catalyst selection showed that the optimum ratio of CoFe2O4 to ZIF-9 was 1∶5.The results showed that the removal rate of rhodamine B with 100 mg/L PMS and 50 mg/L catalyst was 99.7％within 20 min.The prepared CoFe2O4/ZIF-9 composite was a type of efficient and excellent catalyst for remediation of water pollution due to its advantages,e.g.,simple preparation,high catalytic activity,reusable and easy recovery.
