NOVELTY - Preparing oxidized graphene/molecular sieve composite material involves dispersing high silica-alumina molecular sieve in deionized water to formed molecular sieve suspension, then mixed aqueous hydrochloric acid solution with molecular sieve suspension, then acid-treated molecular sieve solution is centrifuged to removed solid phase with deionized water and then dispersed in deionized water to obtained acid-treated molecular sieve suspension, then oxidized graphene aqueous solution is added dropwise to acid-treated molecular sieve suspension. USE - Method for preparing oxidized graphene/molecular sieve composite material (claimed). ADVANTAGE - The method enables to prepare oxidized graphene/molecular sieve composite material has synergistic effect to improves adsorption capacity of pollutant. DETAILED DESCRIPTION - Preparing oxidized graphene/molecular sieve composite material involves dispersing high silica-alumina molecular sieve in deionized water to formed molecular sieve suspension, then mixed aqueous hydrochloric acid solution with molecular sieve suspension, then acid-treated molecular sieve solution is centrifuged to removed solid phase with deionized water and then dispersed in deionized water to obtained acid-treated molecular sieve suspension, then oxidized graphene aqueous solution is added dropwise to acid-treated molecular sieve suspension and then stirred to obtained mixture of graphene and molecular sieves, then mixture of graphene and molecular sieves is heated at 90-130 degrees C for 4-8 hours and then placed in 90-130 degrees C environment and drying for 5-8 hours by grinded into powder oxide graphene/molecular sieve new adsorption material.
