Abstract

A new method for differential pulse voltammetric determination of the priority pollutant 2,4,6-trinitrophenol (picric acid) on a bismuth bulk electrode using evaluation of the signal based on polynomial baseline fitting and subtraction is reported. Linear calibration curves were obtained in an acetate buffer (pH 4.0) solution from 2 × 10−6 to 1 × 10−4 mol L−1 of 2,4,6-trinitrophenol, with limits of detection and quantification of 2.0 × 10−7 mol L−1 and 6.7 × 10−7 mol L−1, respectively. The newly developed method was tested on real sample matrices of drinking and river water.
