Abstract

Section titled ā€œAbstractā€

In this study, a simple, fast and sensitive voltammetric detection using boron-doped diamond (BDD) electrode was proposed for simultaneous quantification of benzene (BZ), naphthalene (NF) and anthracene (AC) from priority organic pollutants class in real tap water. The electrochemical behaviors of individual and simultaneous BZ, NF and AC studied by cyclic voltammetry (CV) on BDD electrode showed a large separation between their oxidation potential, which allowed the development of simple simultaneous detection method. Differential-pulse voltammetry (DPV) technique operated at step potential of 5 mV and modulation amplitude of 200 mV enabled to reach the lowest limits of detection of 0.40 Ī¼M for BZ, 0.04 Ī¼M for NF and 0.70 nM for AC, which is appropriate for water quality control related to their environmental quality standards. No significant influence of chloride ions was found and the method was validated in real tap water and surface water spiked with known concentrations of BZ, NF and AC, which proved the practical utility of the method for water quality control.
