▎ 摘　　要

NOVELTY - A highly-efficient water purification nano-graphene material is prepared by fully dispersing mixture of graphene oxide and alkoxy-modified magnesium oxide in alkane solvent to form a suspension, spraying the suspension into a closed container, reacting at a temperature of 50-70 degrees C to obtain modified graphene oxide, reducing modified graphene oxide with reducing agent in a closed container to obtain modified graphene sponge, crushing modified graphene sponge to 1-30 microns, fully mixing with sulfur-modified zinc oxide in alkane-based solvent and drying. USE - Highly-efficient water purification nano-graphene material. ADVANTAGE - The nano-graphene material has excellent water purification effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for highly-efficient water purification nano-graphene material is prepared by fully dispersing mixture of graphene oxide and alkoxy-modified magnesium oxide in alkane solvent to form a suspension, spraying the suspension into a closed container, reacting under the pressure of less than 0.1 MPa and temperature of 50-70 degrees C to obtain modified graphene oxide, reducing modified graphene oxide with reducing agent in a closed container to obtain modified graphene sponge, crushing modified graphene sponge to 1-30 microns, fully mixing sulfur-modified zinc oxide with particle size of 100-300 nm in alkane-based solvent and drying to obtain nano-graphene material.
