Abstract:

The oxidation of soil organic matter (SOM) and total petroleum hydrocarbon were investigated in two soils at eight different hydrogen peroxide (H2O2) concentrations to determine the optimal H2O2 dosage for the efficient remediation of soils contaminated by crude oil with minimal SOM removal. In our study, H2O2 concentrations up to 1100 mM increased the SOM destruction up to 10%
15% in the two soils while no improvement of the crude oil removal efficiencies was observed. The results indicate that the destruction of SOM significantly limits the oxidation of crude oil because SOM might consume H2O2 more effectively than crude oil at H2O2 concentrations above 1100 mM. In addition, H2O2 concentrations higher than 1100 mM were not expected for both soils because of the extremely rapid H2O2 decomposition, and low H2O2 utilization, of both soils.
