A novel flow injection chemiluminescence (FI-CL) sensor for the determination of sulfamethoxazole (SMZ) was established which using chitosan/graphene oxide-molecularly imprinted polymers (CG-MIP) as recognition element. The SMZ-CG-MIP was synthesized in acetone as solvent and chitosan/graphene oxide for support, using acrylamide as functional monomer, ethylene glycol dimethacrylate as cross-linker and 2,2-azobisisobutyronitrile as initiator. The CG-MIP showed satisfactory recognition capacity for the SMZ. Then the synthesized CG-MIP was employed as recognition by packing into a lab-made tube connected in FI-CL analyzer to establish a novel CL sensor respectively. The CL intensity responded linearly to the concentration of SMZ in the range 1.0×10(-7)mol/L to 2.3×10(-3)mol/L with a detection limit of 2.9×10(-8)mol/L (3σ), which is lower. The relative standard deviation for the determination of 4.0×10(-4)mol/L of SMZ was 1.92% (n=11). The sensor is reusable and has a great improvement in sensitivity and selectivity for CL analysis which applied to the determination of SMZ in drug samples.
