▎ 摘　　要

NOVELTY - Preparation of graphene/chitosan adsorption resin comprises mixing nano anatase titanium dioxide with distilled water using high-speed dispersion machine, high-speed stirring titanium dioxide suspension into graphene oxide solution, mixing chitosan solution in dilute acetic acid mixture, adding mixture containing 1-30% titanium dioxide and 2-5% graphene oxide into chitosan mixture, adding 3.5% glutaraldehyde to mixture, mixing at 60-100 degrees C for 1-4 hours, drying at 90 degrees C, pulverizing and sieving through 200-mesh sieve. USE - Method for preparing graphene/chitosan adsorption resin (claimed) used as catalyst for degradation of dyeing and printing wastewater. ADVANTAGE - The adsorption resin has high adsorption capacity and stability.
