Voltammetric determination of 1,2-diaminoanthraquinone using carbon paste electrode

Abstract

Direct current (DC) voltammetry and differential pulse (DP) voltammetry using a carbon paste electrode (CPE) have been used for the determination of trace amounts of ecotoxic 1,2-diaminoanthraquinone (DAAQ). The limit of determination (L_D) of DAAQ for DC voltammetry was 2 × 10 ^-6 mol l^-1, and for DP voltammetry 2 × 10 ^-7 mol l^-1 under the optimized conditions in a mixed Britton-Robinson buffer pH 12 and methanol (1:9) medium. Adsorptive accummulation of the analyte on the surface of CPE decreased the limit of determination to 2 × 10^-8 mol l^-1 for DP voltammetry. Practical applicability of these newly developed methods was verified on model samples of river water.
