▎ 摘　　要

NOVELTY - Product comprises graphene oxide nano-platelets. USE - The product is useful for binding heavy metals, preferably selenium in wastewater (claimed). ADVANTAGE - The product protects human and environment from selenium toxicity. DETAILED DESCRIPTION - INDEPENDENT CLAIM are included for: (1) process for removing a heavy metal from an aqueous solution, which involves mixing graphene oxide nano-platelets with wastewater containing heavy metal, where the graphene oxide nano-platelets absorb the heavy metal; and (2) A product for use in binding heavy metals in wastewater comprising, magnetic particles grafted to the graphene oxide nano-platelets.
