NOVELTY - Preparing acrylic graft modified graphene with high adsorption performance comprises (1) adding graphene to mixed acid solvent, sonicating for period of time, cleaning and centrifuging, and placing it in oven for drying at certain temperature, (2) taking dried graphene and adding it to the solvent, sonicating for period of time to make it uniformly dispersed, adding acrylic acid (AA) and initiator, washing and centrifuging after heating to certain temperature and stirring for certain period of time, and drying at certain temperature to obtain grafted modified grapheme, and (3) preparing dye solution of certain concentration, taking grafted modified graphene to dye solution, and ultrasonicating for period of time to make the modified graphene and the dye fully contact, and measuring the concentration of the dye after period of time. USE - The method is useful for preparing acrylic graft modified graphene with high adsorption performance. ADVANTAGE - The method: is grafted with long acrylic acid chains; contains large number of oxygen-containing groups; improves the dispersion performance of grapheme; and enhance the adsorption performance of graphene to dyes.
