▎ 摘 要
NOVELTY - Preparing graphene oxide-loaded ferroferric oxide nano composite material, comprises mixing uniformly graphite powder, sodium nitrate, concentrated sulfuric acid and potassium permanganate under ice bath condition to obtain graphene oxide dispersion, then adding ferric ions and ferrous ions into the graphene oxide dispersion, and mixing under alkaline atmosphere to obtain final product. USE - The method is useful for preparing graphene oxide-loaded ferroferric oxide nano composite material. ADVANTAGE - The method: is simple, safe and environmentally-friendly; and has low cost. The composite material: has excellent adsorption capacity for heavy metals and organic dyes in water. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene oxide-loaded ferroferric oxide nano composite material obtained by above method.
