▎ 摘　　要

NOVELTY - Method for concentrating graphene oxide dispersion liquid involves providing graphene oxide dispersion liquid and water-absorbing resin, mixing graphene oxide dispersion liquid and water-absorbing resin before concentrating to obtain a mixed solution, absorbing water in graphene oxide dispersion liquid using water-absorbing resin, and separating graphene oxide dispersion liquid in the mixed liquid and water-absorbing resin after absorbing water. The concentration of concentrated graphene oxide dispersion liquid is 2.5-600 times the concentration of the graphene oxide dispersion liquid. USE - Method for concentrating graphene oxide dispersion liquid. ADVANTAGE - The concentration method of the graphene oxide dispersion liquid has excellent concentration effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for concentrating device of graphene oxide dispersion liquid, which includes a concentrating kettle, a first storage tank for storing the graphene oxide dispersion liquid, a second storage tank for storing water-absorbing resin, and a separating sieve, where the first storage tank, second storage tank and separating sieve are connected with the concentrating kettle.
