Abstract
Sandy soil samples spiked with Bonny light crude oil were subsequently treated with Fenton’s reagent at acidic neutral and basic pH ranges Oil extracts from these samples including an untreated one were analyzed 1 week later with a gas chromatograph to provide evidence of hydrocarbon depletion by the oxidant The reduction of three broad hydrocarbon groups—total petroleum hydrocarbon TPH benzene toluene ethylbenzene and xylene BTEX and polycyclic aromatic hydrocarbon PAH were investigated at various pHs Hydrocarbon removal was efficient with treatment at the acidic pH giving the highest removal of about 96 for PAH 99 for BTEX and some TPH components experiencing complete disappearance The fourringed PAHs were depleted more than their threeringed counterparts at the studied pH ranges
