Abstract

The electrochemical oxidation is a promising process for organic pollutants which are recalcitrant to biological degradation. The anodic oxidation of 1,5-naphthalenedisulfonic acid, hereafter NDS, was evaluated at a Pt anode using in situ generated Ag(II) cation or peroxydisulfate [S2O82-] anion as mediators. Kinetics of the direct chemical oxidation of NDS in the presence of Na ₂S ₂O ₈, and the identification of some oxidation intermediates are also reported. An analysis of the results shows that Ag(II) is characterized by a high-reaction rates, while [S2O82-] performs the oxidation of NDS in a complete way.
