▎ 摘　　要

NOVELTY - Preparation of catalyst having graphene carrier comprises mixing precursor melamine-cyanuric acid-polyimide powder, manganese chloride powder and ferric chloride powder, grinding mixture, calcining and cooling. USE - Method for preparing catalyst having graphene carrier used for catalytic degradation of sulfamethoxazole in wastewater (claimed). ADVANTAGE - The method compounds single iron and manganese on surface of graphene as heterogeneous Fenton-like catalyst which enhances catalytic activity due to super electron transfer ability of graphene. The graphene can also effectively prevent agglomeration of active particles, expose more active sites, and improve removal efficiency of sulfamethoxazole contaminants. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for degradation of sulfamethoxazole in wastewater comprising adding obtained catalyst into wastewater, adjusting pH of mixed system to 3-10, and adding peroxymonosulfate oxidant.
