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.
