NOVELTY - Preparing carbon material-coated spinel iron oxide in-situ growth metal-organic frameworks adsorption the catalytic composite comprises (a) synthesizing or purchasing nano spinel ferrite magnetic nanomaterial by synthesis method, and (b) preparing magnetic spinel iron oxide TFe2O4 coated with carbon material of the nano spinel ferrite, carbon material, and ultrapure water; Where, T is a transition metal element e.g. copper, cobalt, manganese, zinc, and nickel preferably copper, cobalt, or manganese. USE - The carbon material-coated spinel iron oxide in-situ growth metal-organic frameworks adsorption catalytic composite is useful in the preparation of water treatment adsorbents and/or water treatment filter column packing materials, and catalyzing peroxymonosulfate, peroxodisulfate, hydrogen peroxide, ferrate(VI)- and ferrate(VI)-/ hydrogen peroxide to degrade organic pollutants (claimed). ADVANTAGE - The method is simple to operate, has a rich source of raw materials, economical, strong magnetic recovery ability, excellent regeneration performance adsorbs and removes heavy metals and trace organics in water. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for carbon material-coated spinel iron oxide in-situ growth metal-organic frameworks adsorption catalytic composite prepared by the preparation method
