Remediation of Petroleum Hydrocarbons Contaminated Soil by Fentons Oxidation

Author(s): Sylvia Adipah

The study was conducted by Fenton oxidation to efficiently remove contaminants from total petroleum hydrocarbon contaminated soil. IR spectrometry was used to determine the TPH level during soil treatments. In Fenton reaction, using hydrogen peroxide as the catalyst to produce hydroxyl radical could eliminate contaminant in a highly petroleum hydrocarbon contaminated soil. However, there is a need to use an appropriate quantity of reagent and pH (in the acidic medium) to obtain the most efficient in TPH removal in Fenton’s oxidation. In this study, Fenton reaction could remove TPH in soil contaminated approximately; 48% within 2hours with the optimal condition of H2O2: Fe2+ molar ratio of 104, Fenton’s reagent dosage of 50 ml, liquid/soil weight ratio of 15 and under a temperature of 25oC. This indicated that Fenton’s oxidation could be applied to clean up TPH contaminated soils within a short possible time.
