Treatment of Mized Dye Wastewater Using H2O2/Pyridine/Cu(II) System
In this paper, the efficiency of a series of advanced oxidation processes involving the use of a chelating ligand, combined with a transition metal which forms the transition metal complexes to produce reactive radicals was investigated. Previous reports using this H2O2/pyridine/Cu(II) system focused only on the decolourization of a single synthetic dye wastewater. In practice, real dye wastes contain mixture of dyes. Therefore, in this study, we combined two classes of most widely used dyes namely the reactive dye (RD) and disperse dye (DD) in a ratio of (RD: DD)=(0.50: 0.50). Experimental results are assessed in terms of percentage of chemical oxygen demand (COD) reduction, and decolourization. Optimal concentrations were obtained using statistical design of experiment. At optimal concentrations, the percentage of COD reduction was recorded at 86%, while decolourization was 98%.
