▎ 摘　　要

NOVELTY - Preparing graphene oxide modified montmorillonite composition adsorption material comprises (i) dispersing sodium-based montmorillonite in water, adding hydrochloric acid (HCl) to adjust the pH to neutral, and stirring and reacting to obtain sodium-modified montmorillonite after acid modification; and (ii) mixing the acid-modified sodium-based montmorillonite and graphene oxide colloid, and stirring and reacting under ultrasonic, filtering, drying, grinding, and sieving to obtain a composition adsorption of graphene oxide-modified montmorillonite materials, and the mass ratio of the acid-modified sodium-based montmorillonite and graphene oxide is 1-9:1. USE - The graphene oxide-modified montmorillonite composition adsorption material is useful in the adsorption of heavy metal (lead) and organic pollutants (ibuprofen) (claimed). ADVANTAGE - The adsorption material: has large specific surface area, strong adsorption capacity; and the preparation method: is simple, utilizes raw material of lower costs; and utilizes in heavy metal ions and organic pollutants in sewage having strong adsorption capacity, and in the field of sewage treatment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene oxide-modified montmorillonite composition adsorption material, is prepared by the preparation method.
