NOVELTY - Synthesis of magnetic oxide graphene comprises mixing ammonium iron (III) sulfate dodecahydrate (NH 4Fe(SO4)2 12H2O) and ammonium iron sulfate hexahydrate (NH4)2Fe(SO4)2 6H2O at 1.8:1 in ultrapure water, adjusting temperature at 70 degrees C, adjusting pH with ammonia solution (NH4OH) to 3, adding ultrasonic graphene oxide in ultrapure water to mixed solution, mixing for 30 minutes, adjusting pH to 10, reacting for 1 hour, standing at room temperature, washing 3 times with ethanol and ultrapure water and freeze-drying for 24 hours. USE - Method of synthesizing magnetic oxide graphene used for adsorbing heavy metals (claimed). ADVANTAGE - The method is simple to operate and capable of quickly removing heavy metal, does not produce secondary pollution. The graphene has large adsorption capacity, fast absorbing speed, simple operation and low price.
