Abstract: A novel sensor for the determination of terbuthylazine (TBA) based on 3-thiophenemalonic acid (3-TMA) as functional monomer was fabricated by molecularly imprinted technology. The polymeric film was obtained on the gold electrode surface by electrocopolymerization of 3-TMA in the presence of the template molecule of TBA, through the use of cyclic voltammetry (CV). Several important parameters controlling the performance of the molecularly imprinted polymer (MIP) modified sensor were investigated in detail such as the monomer concentration, the electropolymerization cycles and pH. The obtained MIP sensor was highly specific towards newly added TBA and the recognition could be quantitatively analyzed by the differential pulse voltammetry (DPV) to verify the changes in oxidation currents of ferricyanide. In the optimal condition, the response of the imprinted sensor to TBA was linearly proportional to its concentration over the range 2.5 x 10-7 mol/L to 1.2 x 10-4 mol/L, with high sensitivity, good stability and reproducibility (RSD, 2.05%). The method has been successfully applied to the determination of TBA in real samples, with a recovery ranging from 71.2% to 84.9% and a detection limit of 2.0 x 10-8 mol/L (S/N=3).
