磁性石墨烯的制备及其对3-氯代丙二醇的降解作用

Preparation of magnetic graphene and its degradation performance on 3-chloro-1,2-propanediol

采用一步共沉淀法合成了磁性石墨烯(MRE)复合材料,通过XRD、SEM和VSM等技术对其进行了表征分析。将MRE与阴极区域原位生成的H2O2组成电Fenton体系,考察了不同因素对3-氯代丙二醇(CP)去除率的影响。结果显示,溶液中氯离子的去除率为99.58%,COD的去除率为89.30%,TOC的去除率为70.32%。

The magnetic graphene(MRE) composites was synthesized by one-step coprecipitation method. Then the structure was characterized by the XRD,SEM and VSM techniques. The electro-Fenton system was formed by insitu generated H2 O2 in the cathode region and MRE. The effects of various factors on the removal efficiency of 3-chloro-1,2-propandiol(CP) were studied. The results showed that the removal rate of chloride ion in the solution was99.58%,the removal rate of COD was 89.30%,and the removal rate of TOC was 70.32%.
