▎ 摘　　要

NOVELTY - Preparing amino-modified microcrystalline cellulose/graphene oxide aerogel comprises (i) uniformly stirring to mix graphene oxide and cellulose to mixed system of urea, sodium hydroxide, and water to obtain mixed solution, and freezing, and (ii) thawing, stirring to orderly add polyethylenimine and crosslinking agent to mixed solution, drying to form, washing, and freeze-drying to obtain amino-modified microcrystalline cellulose/graphene oxide aerogel, where the crosslinking agent is N,N-methylenebisacrylamide and/or epichlorohydrin. USE - The aerogel is useful in preparing adsorbent (claimed). ADVANTAGE - The method: is simple, and saves time; has high production efficiency, and realizes mass production. The aerogel: is three-dimensional, environmentally friendly, and not easy to scattered in water; has good integrity, good adsorption and good recycling properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the amino-modified microcrystalline cellulose/graphene oxide aerogel.
