NOVELTY - Preparing surface molecularly imprinted polymer of reduced graphene oxide from composite monomer comprises e.g. (i) adding graphene oxide into water, ultrasonicating for 2 hours, then adding hydrazine hydrate solution, concentrated aqueous ammonia and fumed silica, and ultrasonicating for 1-2 hours to obtain dispersion, then heating dispersion at 95-105 degrees C for 0.5-2 hours, washing with water for 2-3 times, filtering, and drying at 60 degrees C under vacuum to obtain reduced graphene oxide, and (ii) adding 4-nitrophenol, methanol, reduced graphene oxide obtained in step (i) and functional monomer into reaction vessel, magnetically stirring for 2 hours, then adding trimethylolpropane trimethacrylate and azobisisobutyronitrile into reaction vessel filled with nitrogen, reacting under water bath at 60-65 degrees C for 28-36 hours, removing solvent p-nitrophenyl acetate by Soxhlet extraction method, and drying to obtain surface molecularly imprinted polymer material of reduced graphene oxide. USE - The method is useful for preparing surface molecularly imprinted polymer of reduced graphene oxide from composite monomer. ADVANTAGE - The method: increases the specific surface area; reduces adsorption and desorption mass transfer resistance; shortens the response time; and improves detection sensitivity. DETAILED DESCRIPTION - Preparing surface molecularly imprinted polymer of reduced graphene oxide from composite monomer comprises (i) adding 10-20 pts. wt. graphene oxide into 200-400 pts. wt. water, ultrasonicating for 2 hours, then adding 0.1-0.5 pts. wt. hydrazine hydrate solution, 1.5-5 pts. wt. concentrated aqueous ammonia and 0.5-1.2 pts. wt. fumed silica, and ultrasonicating for 1-2 hours to obtain dispersion, then heating dispersion while stirring at 95-105 degrees C for 0.5-2 hours, washing with water for 2-3 times, filtering, and drying at 60 degrees C under vacuum to obtain reduced graphene oxide, and (ii) adding 0.3-0.7 pts. wt. 4-nitrophenol, 35-60 pts. wt. methanol, 90-110 pts. wt. reduced graphene oxide obtained in step (i) and 1-4 pts. wt. functional monomer into reaction vessel, magnetically stirring for 2 hours, then adding 2-5 pts. wt. trimethylolpropane trimethacrylate and 25-55 pts. wt. azobisisobutyronitrile into reaction vessel filled with nitrogen, reacting for 15-25 minutes, sealing the vessel, reacting under water bath at 60-65 degrees C for 28-36 hours, removing solvent p-nitrophenyl acetate by Soxhlet extraction method, and drying to obtain surface molecularly imprinted polymer material of reduced graphene oxide, where functional monomer is methacrylic acid, triethanolamine or acrylamide.
