The chemical treatment (ozonation and the Fenton) was applied for remediation of diesel fuel contaminated sand and peat. The chemical treatment of diesel adsorbed in peat resulted in lower diesel removal and required higher addition of chemicals than the chemical treatment of diesel in sand matrix. The reduction of absorbance at 254 nn? gave evidence of aromatics degradation during the chemical treatment. Short-chained linear alkanes (C-11-C-18) were more effectively removed than branched (pristane + phytane) alkanes and long-chained linear alkanes (C-19-C-26) in both sand and peat. A rough estimation and comparison of chemical oxidation treatment (chemicals and energy) costs indicated that the low additions and costs of chemicals make the Fenton and Fenton-like treatment more cost-effective than ozonation. The application of combined chemical + biological treatment may increase the effectiveness of soil remediation and economical feasibility.
