p,p’-DDT[(1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane] is an organochlorine insecticidewidely used by American troops during World War II for controlling illness like malaria, typhus, yellow fever, bubonic plague, especially in Italy and in tropical regions like the South Pacific. The degradation of p,p’-DDT in water by different types of oxidation methods viz. Fenton’s (H2O2 /Fe 2+) oxidation method and electro generated Fenton’s oxidation method was carried out in this study. In classical Fenton’s reaction externally added Fe 2+ facilitate the generation of hydroxyl free radical. In electro generated Fenton’s method, in situ generated Fe2+ facilitate the oxidative cleavage of p,p’-DDT. In classical Fenton’s reaction,76.38% of p,p’-DDT was degraded within 5 minutes of contact time at pH4. Further extending the contact time up to 75minutes, 98% of p,p’-DDT was degraded. In electro generatedFenton’s reaction even in the absence of externally added hydrogen peroxide 50.54% of p,p’-DDT was degraded with in 30minutes of contact time. The degree of degradation was increased to 71.23% with the external addition of 0.5ml of 50% hydrogrn peroxide. Kinetics data obtained from electro generated Fenton’s reaction fitted with pseudo first order kinetics. This study is a baseline study for the removal of p,p’-DDT from industrial effluent system.
