▎ 摘　　要

NOVELTY - Covalent organic framework/graphene oxide adsorbent is claimed. The adsorbent is obtained by loading covalent organic framework material (COF-TpPa-1) onto the surface of graphene oxide (GO) by in-situ synthesis. USE - Used as covalent organic framework/graphene oxide adsorbent. ADVANTAGE - The adsorbent has simple preparation process, larger specific surface area; improves the hexavalent chromium Cr (VI) adsorption performance; and is environmentally friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing covalent organic framework/graphene oxide adsorbent comprising (i) preparing graphene oxide by modified Hummer method, and (ii) preparing covalent organic framework material COF-TpPa-1 supported on graphene oxide.
