▎ 摘  要

NOVELTY - Synthesis of graphene oxide sodium zeolite A (NaA) molecular sieve composite material comprises preparing graphene oxide by improved Hummer method, adding deionized water, ultrasonically dispersing to obtain graphene oxide dispersion liquid, taking NaA molecular sieve, soaking in diluted hydrochloric acid solution, adding the prepared graphene oxide dispersion liquid into molecular sieve suspension, heating and continuously stirring, centrifugally washing the fully reacted suspension, putting into an oven to dry, obtaining solid material, and calcining. USE - The method is for synthesis of graphene oxide NaA molecular sieve composite material used for adsorption of methylene blue (claimed). The composite material is used for dye wastewater treatment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for adsorption of methylene blue using the composite material comprising using the composite material as adsorbent for adsorbing methylene blue solution at pH 10 and 30 degrees C.
