  • Abstract

    In recent years, pollution of soil and groundwater caused by fuel leakage from old underground storage tanks, oil extraction process, oil refineries, fuel distribution terminals, improper disposal and also spills during transferring has been reported. Diesel fuel has created many problems for water resources. The main objective of this research was focused on evaluating the feasibility of using Fenton process in removing TPH from unsaturated soil.  Four parameters namely TPH concentration, H2O2 amount, soil initial pH and molar ratio of H2O2/ Fe(II), were assessed in optimum condition determination. According to data, the optimum conditions were as follows: (i) the reaction time of 1 hour with H2O2 (0.01mol/L, 20 mL) leads to about 60% removal of TPH at neutral pH (7.3), (ii) H2O2/Fe (II) molar ratio of 1:1 (0.01mol/L, 5 mL) after 1 hour of reaction time gives 65% as TPH reduction rate. It appears that stepwise addition of Fenton’s reactant could lead to sustainable removal of pollutant. The results demonstrated that Fenton’s reactant can be used for treatment of contaminated soil with TPH.
