Dechlorination of DDT, DDD and DDE in soil (slurry) phase using magnesium/palladium system
Mg-0/Pd4+ was able to dechlorinate > 99% of extractable DDT (initial concentration of 10 mg DDT kg(-1) of soil) and > 90% of extractable DDT (initial concentration of 50 mg DDT kg(-1) of soil) in soil slurry. Mgo/Pd4+ was also found to be effective in dechlorinating of 50 mg kg(-1) DDD and DDE, in soil aged for varying time periods. GC-MS analyses revealed the formation of 1, 1 -diphenylethane as an end product from DDT, DDE and DDD. To the best of our knowledge this is the first report describing the application Mg-0/Pd4+ system for remediation of DDT, DDD and DDE contaminated soil. We conclude that reductive dechlorination reaction catalyzed by Mg-0/Pd4+ may be a promising system to remediate soil contaminated with DDT and its dechlorinated products such as DDD and DDE.
