▎ 摘　　要

NOVELTY - Manufacture of graphene hydrogel involves preparing a polymer solution by mixing and stirring distilled water and polymer, mixing reduced graphene oxide or graphene oxide with the polymer solution, stirring, preparing stock solution, and irradiating the stock solution. USE - Manufacture of graphene hydrogel used as organic material and ion adsorption material in adsorption of pollutants in liquid fertilizer. ADVANTAGE - The method enables simple manufacture of graphene hydrogel without using harmful crosslinking agent and initiator.
