Abstract: Using the molecular imprinting technique, a novel polymer was prepared by utilizing maleic rosin acrylic acid glycol ester as the cross linking agent, caffeine as template and methyl acrylic acid as functional monomer. A molecularly imprinted polymer membrane was synthesized in vacuum drying oven by free radical polymerization. Cyclic voltammetry (CV), differential pulse voltammetry (DPV) and electrochemical impedance spectroscopy (EIS) characterize the membrane of electrochemical behavior in electrode fabrication process. Under optimum conditions, it was found that the response of peak currents were linear to the concentration of caffeine from 3.0 x 10-6 to 2.7 x 10-3 mol/L (linear regression coefficient=0.9966) with a detection limit of 1.1 x 10-7 mol/L (S/N = 3). The electrochemical sensor displayed excellent repeatability, high sensitivity, long-term stability, and good selectivity. The sensor was applied to the determination of caffeine in coca-cola samples with satisfactory results.
