NOVELTY - The method for preparing highly catalytically active material, involves (1) precooling mixed aqueous solution- containing 6-8 wt.% sodium hydroxide and 10-14 wt.% urea to -12--13 degrees C, adding cellulose, stirring to obtain cellulose solution, (2) adding 1-5 wt.% graphene oxide dispersion to cellulose solution, stirring uniformly, casting, solidifying in a coagulation bath-containing sulfuric acid or sulfuric acid/sodium sulfate to obtain cellulose/graphene oxide hydrogel, (3) immersing hydrogel in mixed aqueous solution-containing 1-20 wt.% ferric chloride and ferrous chloride, immersing in 1-5 wt.% aqueous solution of sodium hydroxide to obtain iron(II, III) oxide nanoparticles and washing with water to obtain final product. USE - Method for preparation of highly catalytically active material for heterogeneous Fenton reaction used in wastewater treatment such as printing and dyeing wastewater treatment, oily wastewater treatment, and phenol-containing wastewater treatment. ADVANTAGE - The environmentally-friendly method enables simple and economical preparation of highly catalytically active material with synergistic effect and high ability to remove refractory organic pollutants.
