Treatment of diazo dye Reactive Green 19 by anodic oxidation on a boron-doped diamond electrode

다국어 초록 (Multilingual Abstract)

The anodic oxidation of diazo dye Reactive Green 19 on a boron-doped diamond electrode was investigated. A membrane-free reactor was used to evaluate the effect of chloride concentration (0–0.5 M), current density (100–500 A m2), pH (3–11) and stirring rate (250–750 rpm) on color and TOC removal. Complete decolorization was obtained in less than 30 min, whereas total mineralization was never achieved within 3 h of electrolysis. Color removal was significantly enhanced by increasing chloride concentration and, to a lesser extent, current density and stirring rate. TOC removal was positively affected by current density, pH and chloride concentration.
