▎ 摘  要

NOVELTY - A porous graphene oxide composite material for wastewater treatment comprises 3-5 pts. wt. graphene, 2-3 pts. wt. layered silicate, and 3-5 pts. wt. gelatin. USE - Porous graphene oxide composite material for wastewater treatment (claimed), such as absorbing of dye wastewater. ADVANTAGE - The material has good mechanical strength, excellent adsorptivity, and uniform dispersion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of porous graphene oxide composite material which involves mixing graphene oxide and layered silicate, ultrasonic stirring to obtain aqueous solution, adding gelatin to obtain mixed liquid, adding acid solution, regulating solution pH to 4.5-6.5, transferring in mold, standing, crosslinking to obtain mixed glue solution, crosslinking-reacting mixed glue solution to obtain gel, and freeze-drying.
