▎ 摘　　要

NOVELTY - Preparing modified graphene oxide composite aerogel dye adsorbent involves obtaining intercalation composite hydrosol by chitosan, konjac glucomannan, starch and graphene oxide dispersion liquid. The hydrogel is formed under the action of the eight-arm polyethylene glycol carboxyl group and citric acid crosslinking agent, and then freeze-dried to prepare the aerogel, that is, the modified graphene oxide composite aerogel dye adsorbent. USE - Method for preparing modified graphene oxide composite aerogel dye adsorbent in the purification treatment of dye wastewater (all claimed). ADVANTAGE - The method has synergistic adsorption effect of multi-active groups and graphene oxide nanosheets. It has a high adsorption removal rate for general anionic and cationic dyes and acid and direct dyes. It has fast adsorption rate, large adsorption capacity and easy recovery and reuse.
