Abstract

This study is focused on the application of a carbon film electrode for the determination of micromolar concentrations of pesticide 2-nitrophenol using modern voltammetric methods. For the determination of 2-nitrophenol, direct current (DCV) and differential pulse (DPV) voltammetry were chosen. The following optimal conditions for the determination of 2-nitrophenol were found: Britton-Robinson buffer of pH 5.0 for DCV and pH 6.0 for DPV, and the regeneration potential cycles (E in = 0 mV, E fin = 0 mV). Under these conditions, limit of quantification was found to be 1.2 × 10-6 mol dm-3 for DCV and 2.0 × 10-6 mol dm-3 for DPV in deionized water. The limit of quantification for model samples of drinking water was 3.0 × 10-7 mol dm-3 for DCV and 1.0 × 10-6 mol dm-3 for DPV. The applicability of carbon film electrode for the determination of micromolar concentrations of 2-nitrophenol based on cathodic reduction of present nitro group and in model samples of drinking water was confirmed.
