▎ 摘　　要

NOVELTY - Supergravity preparation of graphene oxide modified nano zero-valent iron composite material involves mixing graphene oxide and metal salt to obtain mixed solution, adding reducing agent to the supergravity reactor, reacting, separating reaction product is magnetically, washing to neutral with deionized water or absolute ethanol, freezing and drying. The metal salt is a ferrous salt or an iron salt. USE - Supergravity preparation of graphene oxide modified nano zero-valent iron composite material. ADVANTAGE - The composite is economically prepared by simple one step process in short reaction time. The prepared graphene oxide modified nano zero-valent iron composite material has excellent dispersibility and stability, high reactivity, and small particle size.
