Abstract
In this study, Fenton oxidation was applied to railroad track ballasts contaminated with small amounts of oil. In order to perform the experiment on Fenton oxidation, petroleum contaminated ballast was collected from the railroad track and experiments on major factors of the remediation process were implemented in the laboratory. Then, the feasibility of insitu Fenton oxidation was investigated for the railroad track that was partially contaminated with oil. As a result, the residual TPH concentration of ballast was reduced to about 1,000 mg/kg-ballast in laboratory experiments using 0.1 mol Fe/L $H_2O_2$. Due to the drainage structure of the track bed, a considerable amount of $H_2O_2$ was released below the ballast without the sufficient reaction with the contaminated ballast; therefore, additional studies are necessary for the effective field application of Fenton oxidation.
