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 (LD) 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.
