▎ 摘　　要

NOVELTY - Oxidized graphene/polymer gel adsorbent preparation involves adding polyacrylamide into oxidized graphene solution to form a blending solution, and then stirring and mixing uniformly under normal temperature to obtain an oxidized graphene/polyacrylamide gel. The obtained adsorbent is freeze-dried to obtain the gel adsorbent. USE - Method for preparing oxidized graphene/polymer gel adsorbent (claimed) for purifying dye wastewater, preferably cationic dye wastewater. ADVANTAGE - The method prepares the oxidized graphene/polymer gel adsorbent in a s simple, convenient, cost-effective and eco-friendly manner with high adsorption capacity and easy recycling. The obtained gel adsorbent quickly and efficiently adsorbs cationic dye from the waste water. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic photograph of the preparing oxidized graphene/polymer gel adsorbent.
