Abstract

Metallic Fenton reaction was found to be more effective than classical Fenton reaction in decomposing Pentachlorophenol (PCP) in contaminated soil. The combination of metallic iron and hydrogen peroxide was used in column leaching experiments to simulate heap and in-situ soil remediation. PCP in the contaminated soil was effectively decomposed by 32% in 24 hours leaching tests, and by 41% in 48 hours leaching experiments. PCP destruction was further increased to 52% in the 48 hours leaching by lowering the solution pH to 1.8. Other than ferric oxide and carbon dioxide, no byproducts were found at the end of the reaction.
