NOVELTY - Preparing magnetic nano-composite material involves using alcohol as solvent containing 1-5 carbon atoms, dissolving graphene/polyaniline composite material, ferric chloride and sodium acetate in ratio 1-3:1-5:5-10 in solvent and ultrasonically processing at high pressure in reaction kettle to react to obtain magnetic graphene polyaniline nano-composite material. The power of the ultrasonic treatment is 300-500 Watts for 0.5-1.5 hours. The reaction is performed at 150-250 degrees C for 4-48 hours. USE - Method for preparing magnetic nano-composite material. ADVANTAGE - The method enables to prepare magnetic nano-composite material which has excellent adsorption efficiency and is prepared in simple manner.
