▎ 摘　　要

NOVELTY - Preparing hybrid graphene magnetic catalytic particle electrode comprises (i) adding montmorillonite and sucrose into ethylene glycol to obtain white, uniform suspension after ultrasound; (ii) adding iron trichloride hexahydrate, anhydrous sodium acetate and polyethylene glycol into ethylene glycol and mixing uniformly, adding into suspension, stirring, adding uniformly stirred solution into a polytetrafluoroethylene autoclave for heating, mixing black solid with ethanol, drying in a vacuum drying oven, grinding to obtain black powder; (iii) mixing black powder with polyvinyl alcohol aqueous solution, placing on the rolling pill board for granulation to obtain round particles, freeze-drying and calcining under nitrogen protective atmosphere. USE - The electrode is useful for three-dimensional electro-Fenton degradation of anti-coronavirus medicine arbidol in water (claimed). ADVANTAGE - The method increases the adsorption site and specific surface area of the catalytic particle electrode; and improves the adsorption capacity of the catalytic particle electrode, catalytic ability and degradation effect of three-dimensional electric Fenton technology. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for three-dimensional electro-Fenton degradation of anti-coronavirus medicine arbidol in water.
