▎ 摘  要

NOVELTY - Method for synthesizing bimetallic tin oxide atomic level hybrid magnetic beads modified graphene material-titanium involves dissolving graphene material in concentrated sulfuric acid and stirring for 6-12 hours, centrifuging, water washing, drying product, then adding iron(III) chloride hexahydrate, trisodium citrate, sodium acetate and polyethylene glycol to product, reacting mixture in high pressure reaction kettle at 200 degrees C for 9.5-10.5 hours, cooling mixture to room temperature, and magnetically separating and washing obtained product. USE - The method is useful for synthesizing bimetallic tin oxide atomic level hybrid magnetic beads modified graphene material-titanium (claimed). ADVANTAGE - The method is simple and cost-effective. DETAILED DESCRIPTION - Method for synthesizing bimetallic tin oxide atomic level hybrid magnetic beads modified graphene material-titanium involves dissolving graphene material in concentrated sulfuric acid and stirring for 6-12 hours, where ratio of graphene material to concentrated sulfuric acid is 0.40-0.50 g:50-100 ml, centrifuging, water washing until washing liquid becomes neutral, drying product at 50 degrees C, then adding iron(III) chloride hexahydrate, trisodium citrate, sodium acetate and polyethylene glycol in ratio of 0.18-0.20 mg:0.15-0.20 g:2.5-2.6 g:1.8-2 g to product, reacting mixture in high pressure reaction kettle at 200 degrees C for 9.5-10.5 hours, cooling mixture to room temperature, and magnetically separating and washing obtained product.
