摘要:Chemical degradation of Organochlorine pesticide (OCPs) in hydrodechlorination reactions were first systematically investigated using dichloro diphenyl trichloroethane (DDT) as the model pesticide. The reaction of DDT produced an equimolar amount of HCl and DDE resulting from initial attack and was identified using GC-ECD. The produced DDE was dechlorinated by using Fe/Ni catalysts with a solution of NaOH in 2-propanol/methanol (99:1 v/v) at temperature below 82 oC. The developed method efficiently converted DDT in the range of 3.5 – 3500 mg/l to chlorine-free product within 240 minutes. Chloride ions concentrations were also identified as a product using Ion Chromatography..
