Anodic differential pulse voltammetric determination of 2-nitrophenol at a non-traditional carbon film composite electrode
Original language description
A new method was developed for the determination of 2-nitrophenol (2-NP) by differential pulse voltammetry (DPV) employing the anodic oxidation of the present hydroxyl group using a non-traditional carbon film composite electrode (CFCE) based on a microcrystalline natural graphite-polystyrene composite film. Britton-Robinson (BR) buffer of pH 6.0 was found to be an optimal supporting electrolyte. Cleaning regeneration potentials E-in = +1300 mV and E-fin = 0 mV had to be applied before each measurement to get rid of problems connected with electrode passivation. Linear calibration curves were obtained in the concentration range from 0.2 to 10 mu mol L-1 of 2-NP for both tested matrices (deionized and drinking water). Limit of quantification (LOQ) for DPV at the CFCE was found to be 0.2 mu mol L-1 and 0.1 mu mol L-1 for deionized and drinking water, respectively.
