采用湿式浸渍法,将6种含过渡金属(Cu,Fe,Zn,Ni,Mn,Ce)元素的化合物负载在活性炭(AC)上,制得6种催化剂AC/M(M=Cu,Fe,Zn,Ni,Mn,Ce),在室温条件下,催化臭氧化处理苯酚溶液和印染污泥.催化剂AC/M通过Boehm滴定、XRD和BET分析进行表征.苯酚的3种降解方法中,AC/M催化剂的臭氧催化最好,AC/M吸附处理次之,单独臭氧处理的效果最差.在苯酚的降解处理过程中,AC/M催化臭氧化处理苯酚溶液的效率依次为:AC/Fe＞ AC/Zn＞ AC/Ni＞ AC/Ce＞ AC/Cu＞ AC/Mn.AC/M催化剂催化臭氧化效果随溶液pH值的增大而增强.AC/M催化剂处理印染污泥的效率依次为:AC/Fe＞ AC/Zn＞ AC/Ce=AC/Ni＞AC/Cu＞ AC/Mn,AC/Fe催化臭氧化处理印染污泥可使污泥中有机质含量降低8.17％.
