Abstract: In this paper, a sensitive sensor based on the molecularly imprinted polymer (MIP) of o-phenylenediamine was proposed, and its configuration and performance were studied. The progress of the electro polymerization is performed in a acetate buffer solution (pH = 5.7) containing 1.0mmol/L nicotinamide and 3.0mmol/L o-phenylenediamine on the surface of a glassy carbon electrode. The molecularly imprinted polymer membrane was characterized using cyclic voltammetry. The linear range is 0.01 μmol/L ~ 1.1 μmol/L with a detection limit of 4.5 x 10-9 mol/L. The sensor was sensitive, selective, easy in preparing with a low price. It was applied to determination of trace nicotinamide in beverage.
Template and target information: nicotinamide
