▎ 摘　　要

NOVELTY - Preparing renewable graphene oxide (GO)/nano zero-valent iron (nZVI) composite comprises mixing nano zero-valent iron with graphene oxide in a solvent to obtain a solid precipitate, and performing magnetic separation to obtain the composite. USE - The composite is useful for removing organic pollutants from wastewater (claimed), adsorption and oxidizing degradation of pollutants, treating highly-diluted pollutants. ADVANTAGE - The composite: has macro-structure; establishes a dynamic system having a pH regulation character; and is magnetically separable; and enriches and concentrates the pollutants to oxidize and degrade the pollutants; has higher efficiency; and greatly reduces treatment cost. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) graphene oxide/nano zero-valent iron composite prepared by the above mentioned method; and (2) use of the graphene oxide/nano zero-valent iron composite for removing organic pollutants from wastewater, comprising adding the composite to the wastewater, completely adsorbing, magnetically adsorbing antibiotics, and separating the composite.
