▎ 摘　　要

NOVELTY - A diaminobenzene-functionalized graphene-doped activated carbon composite electrode is prepared by uniformly mixing diaminobenzene-functionalized graphene as a conductive additive and activated carbon using a binder to construct composite material, carrying out film forming by pressing, fixing the composite material on an electrode sheet and vacuum drying. USE - Diaminobenzene-functionalized graphene-doped activated carbon composite electrode is useful as an anode and a cathode of an electric adsorption device for secondary biochemical effluent desalination. ADVANTAGE - The diaminobenzene-functionalized graphene-doped activated carbon composite electrode has improved specific surface area, adsorption capacity and desalination efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of diaminobenzene-functionalized graphene-doped activated carbon composite electrode.
