NOVELTY - Preparing magnetic oxide graphene adsorbent comprises oxidizing graphite powder to oxidized graphite, then ultrasonically stripping into graphene oxide, adding 1-10 g ferrous salt, 1-10 g ferric salt, 0.1-5 g graphene oxide, 100-500 ml distilled water, ultrasonicating using ultrasound device for 1-5 hours, then adding ammonia-water for adjusting pH to 8-12, then ultrasonicating for 1-5 hours, washing the obtained product by centrifugal separation method to neutral, and drying in an oven at 40-100 degrees C under vacuum to obtain final product. USE - The graphene adsorbent is useful for adsorption wastewater in dye (claimed). ADVANTAGE - The graphene adsorbent is capable of adsorbing dye (claimed), and has good effect in removing organic matter and dye in waste water.
