Abstract

In this study, the remediation of diesel contaminated soil was attempted with ozone treatment and Fenton reaction. About 10% of initial diesel concentration was removed by the ozone saturated solution. The pseudo-first order decomposition constant of diesel contaminated soil in the presence of 5% of hydrogen peroxide with 1.82, 2.82, 4.82, 6.82, and 11.82% of iron contents was 0.0228, 0.0308, 0.0482, 0.0471, and 0.0592 $min^{-1}$ respectively. The decomposition constant of the diesel was 0.0064 $min^{-1}$ with the addition of ozone saturated solution only. On the addition of ozone saturated solution in the presence of 5% hydrogen peroxide and 5% iron, the decomposition constant of the diesel was 0.0850 $min^{-1}$. These results indicated that the decomposition rate was 190% faster than without the addition of ozone saturated solution. Thus, the application of both ozone and the fenton reaction is promising for the remediation of the diesel contaminated soil.
