▎ 摘　　要

NOVELTY - Preparing iron alginate-graphene oxide catalytic material comprises (a) adding graphene oxide solution and sodium alginate, stirring well to obtain graphene oxide sodium alginate solution, (b) adding the graphene oxide-sodium alginate solution drop wise to the mixed aqueous solution of iron (II) sulfate heptahydrate and ascorbic acid, allowing to stand, reacting and (c) filtering, washing and drying to obtain iron alginate-graphene oxide catalytic material. USE - The method is useful for preparing iron alginate-graphene oxide catalytic material. ADVANTAGE - The catalytic material has efficient catalytic effect in the treatment of phenol wastewater; is spherical, easy to separate from pollutants and can be recycled. The method is inexpensive and simple to prepare and easily obtains raw materials. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a iron alginate-graphene oxide catalytic material prepared by the above method; and (2) use of iron alginate-graphene oxide catalytic material comprising adding catalytic material and hydrogen peroxide to the phenol waste water and degrading the phenol.
