Advanced Oxidation Processes and DDT Degradation Kinetics with H 2 O 2 /Sunlight
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 4
Abstract
Advanced Oxidation Processes (AOPs) are a group of oxidation processes carried out to remove harmful persistent organic pollutants (POP) from water, which are otherwise very hard to remove. The last century saw a glut of chemical industries rising up to meet the needs of modern day commodity chemicals like detergents, dyes, pesticides and so on. Treatment of effluents of such industries has always been tenacious and cumbersome. Advanced oxidation process has now become the inevitable technology for the future to tackle the inexorable problems of pollution. Advanced oxidation process is a set of various methods by which dangerous organic pollutants are broken down to innocuous sub species and carbon dioxide. Normally this is done using a strong oxidizing agent such as H2O2 or O3. These species are dissociated to form oxygen radicals either by irradiation of UV or by suitable catalysts such as Fenton`s reagent or TiO2. Of all the POPs present, it is pesticides that the general public is most worried about. In our research, we have studied the advanced oxidation using H2O2/Sunlight system on two pesticides namely DDT and Dicofol. Time allowed for the process, the pH at which process is carried out, and the amount of H2O2 used for the process were found out to be the major parameters on the rate of reaction. The entire study was carried out using an Agilent Gas Chromatograph. As the result, over 50% reduction in pesticide concentration over a period of 4 hours was found out. The decomposition of DDT, both of its o, p and p, p isomers, was found to follow first order kinetics. The effect of parameters on the reaction kinetics was also studied .This research study provides the kinetic data to design and develop an advanced oxidation treatment plant. It also provides an insight into the application of AOP in the pesticide industry effluent treatment. AOP when implemented along with current methods like solvent extraction, is an eco-friendly and economically feasible option.
