Abstract: Aiming at the characteristics of low catalytic effect of Fe²⁺ in homogeneous Fenton reaction,and complicated subsequent treatment process,the transition metal elements are to be loaded on γ-Al₂O₃,so as to prepared heterogeneous catalyst,which has been used for the degradation of 10 mg/L of phenol solution. The optimal mass ratio of the elements is m(Mn):m(Fe):m(Cu):m(V):m(Ni)=3:1:2:2:1. At normal temperature,pH=3,m(catalyst):m(hydrogen peroxide)=1,and mass of catalyst 5 g. Under these conditions,when 1 L 10 mg/L of simulated wastewater is degraded, the phenol removing rate can reach 98.5%,and COD degradation rate can be above 90.0%.

摘要： 针对均相Fenton反应中Fe²⁺的催化效果较低、后续处理过程复杂的特点，将过渡金属元素负载于γ-Al₂O₃上，制得非均相催化剂，用于10 mg/L苯酚溶液的降解。各元素最优质量比为m（Mn）：m（Fe）：m（Cu）：m（V）：m（Ni）=3：1：2：2：1；常温下pH为3、m（催化剂）：m（双氧水）=1、催化剂质量为5 g时，降解1 L质量浓度为10 mg/L的模拟苯酚废水，苯酚去除率可达98.5%，COD降解率可达90.0%以上。
