▎ 摘　　要

NOVELTY - Preparing graphite material modified red mud-based Fenton catalyst with magnetic separation performance, comprises (i) placing the red mud into an acid solution, stirring, centrifuging, washing solid water, drying, dispersing the dried product in the deionized water to obtain red mud suspension, (ii) adding carbon-containing organic molecule and graphite oxide material in the red mud suspension, uniformly stirring and mixing, centrifuging and washing, taking solid and drying to obtain red mud mixed catalyst, and (iii) calcining the red mud mixed catalyst at high temperature under inert atmosphere, and cooling. USE - The method is useful for preparing graphite material modified red mud-based Fenton catalyst with magnetic separation performance, which is useful in wastewater treatment (claimed). ADVANTAGE - The method; provides catalyst, which is environmental friendly and achieves the magnetic separation effect by means of the magnetism of the iron-containing oxides in the red mud after the degradation reaction is completed. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: the graphite material modified red mud-based Fenton catalyst with magnetic separation performance prepared by above mentioned method; and use of graphite material modified red mud-based Fenton catalyst with magnetic separation performance in wastewater treatment, comprising mixing the modified red mud-based Fenton catalyst, the aqueous solution of organic pollutants and the oxidant, carrying out the reaction under the illumination of a light source, degrading pollutants, and adsorbing the catalyst in the aqueous solution using an external magnetic field.
