A new approach for the degradation of high concentration of aromatic amine by heterocatalytic Fenton oxidation: Kinetic and spectroscopic studies

Abstract

In the present investigation an attempt was made to degrade aniline in the synthetic effluent by homogeneous and heterogeneous Fenton oxidation process. Experiments were carried out under the batch and continuous operating conditions. The effect of time, pH and the mass of mesoporous activated carbon on the degradation of aniline in the synthetic wastewater was critically examined through eexperimental design and optimization by central composite design (CCD) under the response surface methodology (RSM). The kinetic constants and the thermodynamic parameters for the oxidation of aniline in synthetic wastewater were determined. The degradation of aniline in synthetic wastewater was confirmed using FT-IR, NMR and UV–visible spectroscopy.
