NOVELTY - Phenyl magnesium bromide is dispersed to tetrahydrofuran, carbon disulfide and brominated magnetic graphite alkene are added to mixture, separated and washed, to obtain functional magnetic graphite alkene. A template molecule is dissolved in a solvent, functional monomer is added to dissolved mixture, functioning for predetermined time, and functional magnetic graphite alkene, cross-linking agent and initiator are added to product under protection of inert gas and polymerized, to obtain magnetic graphene-doped polymer. USE - Preparation of magnetic graphene-doped polymer used for chemiluminescence sensor. ADVANTAGE - The method efficiently and economically provides magnetic graphene-doped polymer having high selectivity and absorption capacity. DETAILED DESCRIPTION - Graphite powder, sodium nitrite and potassium permanganate are added to concentrated sulfuric acid, reacted for predetermined time, water is added to mixture and continuously reacted for predetermined time. Hydrogen peroxide is dripped to mixture, filtered and then washed, to obtain graphite alkene oxide. The graphite alkene oxide is dispersed in solution containing ammonium ferrous sulfate and ferric ammonium alum, ultrasonically processed, aqueous ammonia is added to mixture, stirred, reacted, separated, washed and dried, to obtain magnetic graphite alkene. The magnetic graphite alkene is dispersed to methylbenzene solution containing sulfoxide chloride, reflown for predetermined time, washed and vacuum-dried, to obtain acyl chlorinated magnetic graphite alkene. The product is reacted with 2-ethoxy-2-bromo isobutyric acid, triethylamine is added to reaction mixture, separated, washed and dried, to obtain brominated magnetic graphite alkene. Then, phenyl magnesium bromide is dispersed to tetrahydrofuran, carbon disulfide and brominated magnetic graphite alkene are added to mixture, separated and washed, to obtain functional magnetic graphite alkene. A template molecule is dissolved in a solvent, functional monomer is added to dissolved mixture, functioning for predetermined time, and functional magnetic graphite alkene, cross-linking agent and initiator are added to product under protection of inert gas and polymerized, to obtain magnetic graphene-doped polymer.
