Abstract: Industries occupy a place of prominence in the Indian economy in view of its massive potential for employment, growth and exports. The aniline derivatives are dye intermediates with wide applications and some of the most extensively used derivatives are 2-nitroaniline, 3-nitroaniline and 4-niroaniline. The disposal of untreated effluents containing these derivate are extremely harmful to the receiving water bodies; new and improved treatment methods are being researched to effectively degrade and remove these harmful compounds present in the industrial effluents before disposal into the environment. In the present study, some of the major toxic aniline derivatives from effluents using Fenton and photo Fenton oxidation methods was carried out. A number of physical methods, chemical methods, and biological methods are available for the treating wastewaters. The degradation of 2-NA in water by Fenton & Photo-Fenton advanced oxidation process was investigated in this study. The effect of pH (2mM-4mM), initial concentration (0.5mM-2.5mM), H2O2 concentration (2mM-21.5mM), Fe2+ concentration (0.05mM0.275mM) on the rate of degradation was investigated. The process was optimized with 2-NA removal efficiency of 89.1 %. The photo Fenton oxidation was carried out to increase the removal efficiency of 2-NA. The Kinetic studies were carried out to optimize the reaction time in Fenton and Photo Fenton process.
