In the present investigation an attempt was made to degrade organic pollutants in the textile effluent by homogeneous and heterogeneous Fenton systems. Experiments were carried out under the batch as well as under the continuous operating conditions. The effect of time, pH. H(2)O(2) concentration, FeSO(4).7H(2)O concentration and the mass of mesoporous activated carbon on the degradation of organics in the wastewater were critically examined. The kinetic constants and the thermodynamic parameters for the oxidation of organics in wastewater were determined. The quantitative removal of COD, BOO and TOC from the wastewater was evaluated. The degradation of organics in textile wastewater was confirmed through FT-IR. UV-Visible spectroscopy, and cyclic voltammetry. (C) 2011 Elsevier B.V. All rights reserved.
