▎ 摘　　要

NOVELTY - Preparing polyethylenimine-modified graphene oxide/carboxymethyl cellulose/polyvinyl alcohol (PEI-mGO/CMC/PVA) composite material involves using PEI-mGO, CMC, PVA as precursor, dispersing and dropping PEI-mGO to CMC and PVA in the mixed solution, stirring for 2-4 hours, processing by freezing-thawing method, removing solvent water to obtain PEI-mGO/CMC/PVA three-dimensional aerogel material. USE - Method for preparing polyethylenimine-modified graphene oxide/carboxymethyl cellulose/polyvinyl alcohol (PEI-mGO/CMC/PVA) composite material. ADVANTAGE - The method enables to prepare polyethylenimine-modified graphene oxide/carboxymethyl cellulose/polyvinyl alcohol (PEI-mGO/CMC/PVA) composite material is non-toxic and has fast fast removal rate to 90%.
