摘　　要：在初始pH=3的条件下,以金属有机配合物[Cu2(μ4-L)2]n为非均相催化剂,过硫酸钠(Na2S2O8)为类Fenton体系的氧化剂,探讨了配合物催化剂对甲基橙的降解性能,结果显示,反应前40 min,能有效降解60%的甲基橙,而当反应时间超过110 min后,有效降解率高达88%;同样条件下,不添加配合物催化剂,甲基橙的降解率只为15%。Methyl orange degradation was carried out at pH = 3 based on metal-organic complex, [Cu2（P-4L）2]n. as heterogeneous catalysis and Na2S208 as oxidant of Fenton system. The results reveal that the degradation efficiency is 60 % before 40 rain of reaction time, and the value up to 88 % alter the reaction time reach to II 0 min. At the same conditions, without adding complex catalyst, the degradation rate of methyl orange only 15 %.
