▎ 摘  要

NOVELTY - A composite adsorbent comprises graphene oxide/calcium alginate supported in three-dimensional network framework of melamine sponge filled with pores of melamine sponge. USE - Composite adsorbent used in adsorption of metal ions and treatment of heavy metal contaminated wastewater (all claimed). ADVANTAGE - The composite adsorbent has high adsorption performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite adsorbent which involves preparing a graphene oxide solution, adding sodium alginate to the graphene oxide solution, uniformly stirring to obtain a gel solution, pretreating melamine sponge, fully immersing in the gel solution, drying to obtain a graphene oxide/alginate-loaded melamine sponge precursor, immersing graphene oxide/alginate-loaded melamine sponge precursor in a calcium salt solution, subjecting to constant temperature shaking, washing and drying.
