▎ 摘　　要

NOVELTY - Method for preparing graphene oxide-based adsorbent, involves (i) adding graphene oxide to water and ultrasonically processing to obtain a graphene oxide solution, (ii) adding hydrotalcite to the graphene oxide solution, ultrasonically processing and mechanically stirring to obtain a mixed solution, and (iii) after leaving still the mixed solution, layering phenomenon occurs, removing the supernatant liquid, and drying and grinding the precipitate. USE - The method is useful for preparing graphene oxide-based adsorbent for adsorbing water pollutants (all claimed). ADVANTAGE - The method provides the adsorbent which has excellent adsorption effect on water pollutants, effectively reduces the agglomeration of graphene oxide, and has simple operation, and since the agglomeration of graphene oxide in the composite material is suppressed, the adsorption performance of the composite material is better.
