▎ 摘　　要

NOVELTY - An adsorbent comprises 1 pts. wt. attapulgite, 20-200 pts. wt. water and 0.02-0.1 pts. wt. sodium hexametaphosphate together with an aqueous solution of graphene oxide, attapulgite and graphene oxide at a mass ratio of 0.1:1-10:1. USE - Adsorbent used for water treatment. ADVANTAGE - The adsorbent has good hydrophilicity, strong adsorption capacity, low cost, and high material recycling efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of adsorbent comprising: (A) carrying out stirring, standing and delamination method, immersing attapulgite in water, using sodium hexametaphosphate as dispersant, purifying natural attapulgite, and preparing into attapulgite suspension; (B) taking attapulgite and graphene oxide respectively, carrying out ultrasonic processing hydrothermal reaction, using attapulgite embedded to plugging oxidation of graphene surface to obtain the attapulgite and graphene oxide composite adsorbent solution; and (C) drying attapulgite with graphene oxide composite adsorbent aqueous solution to obtain the adsorbent product.
