Effect of Hydrogen Peroxide Concentration in Remediation of Oil-contaminated Soils with Use of Fenton Reaction

Abstract

Refining oil-contaminated soils has a great importance especially in oil producer countries such as
Iran. Different methods have been provided to eliminate oil contaminations from soil. The aim of this study
was to investigate the effect of Hydrogen peroxide concentration in refining oil-contaminated soils with Fenton
chemical method. To do this, a calcareous soil complex sample was collected around the Tehran oil refinery
and treated with 10 and 20 percent petroleum in three replications. After reaching to balance conditions, the
sample was treated using0.01, 0.02,0.12,0.24,0.47 and 0.71 equivalent of Hydrogen peroxide. The results
indicated that in all level of H2O2, the eliminating efficiency in 10 percent was more than 20 percent treatment.
Also a significant difference between the levels of hydrogen peroxide used in the removal of oil pollution in
both surface concentrations was obtained (P<0.01).
