▎ 摘　　要

NOVELTY - Modified carbon nano-material comprises graphene oxide, humic acid, ferrous sulfate and nano-iron. USE - The nano-material is useful for adsorption and degradation of organic pollutants in water, where the organic pollutant is naphthol (claimed). ADVANTAGE - The nano-material has large specific surface area, high reducibility, is easy to agglomerate and not stable after being reduced, is simple in preparation and is economical, has excellent water phase stability, is environmentally-friendly, and has excellent adsorption performance and high degradation efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of preparing the modified carbon nano-material comprising (i) performing ultrasonic treatment on graphene oxide in deionized water to obtain colloidal graphene oxide, refrigerating and storing, (ii) adding colloidal graphene oxide to sealed container, introducing nitrogen, adding nano-iron or ferrous sulfate reducing agent, avoiding light balance to obtain reduced graphene oxide, preparing the product, adding ferrous sulfate and humic acid in the system at the same time, and (iii) collecting the product, cleaning and drying.
