▎ 摘 要
NOVELTY - The preparation of graphene/activated carbon composite gel adsorbent involves (A) pulverizing activated carbon into powder of 10 mu m or less, immersing in alkaline reduction pore-forming solution until fully absorbed, and filtering out the material, (B) dispersing the filtered activated carbon in graphene oxide solution, placing in hot water tank, rotating up and down during the hydrothermal process and cooling after the reaction is completed, (C) releasing water, washing with pure water and drying. USE - Preparation of graphene/activated carbon composite gel adsorbent for mask. ADVANTAGE - The method enables preparation of graphene/activated carbon composite gel adsorbent ensuring superior adsorption capacity by simple and environmentally-friendly process.
