Oxidation technique has been used to remediate the organic compounds from the contaminated soils with petroleum hydrocarbons due to its high oxidation capacity. Among various oxidizing chemicals, SOREM™ (Potassium monopersulfate & Sodium persulfate compound, Kings field Inc.) which produced SO4 radical in water has received a great attention. This radical has shown high remediation efficiency than OH radical produced by hydrogen peroxide. In this study, soil contaminated with total petroleum hydrocarbon (TPH) was treated with SOREM™. Various amounts of SOREM™ (0.5, 1, 3, 5%) were applied to soil spiked with 20,000ppm diesel (equivalent to 313.4 ppm TPH) for 10, 30, 60, and 120 min, respectively. The residual TPH in soil after treatment of SOREM™ was extracted with a mixture of methylene chloride and acetone (1:1). Aliquot of extraction was analyzed by GC-FID (Hewlett-Packard, 5890 II) with a capillary column (Ultra-2, 25 m × 0.20 mm × 0.33 μm). The temperature programming was used at 45 ℃ for 2 min increased at the rate of 10 ℃ / min to 310 ℃ for 25 min and the injector temperature was 280 ℃. The soil used in this study was consisted of sand (54.55%), silt (31.83%), and clay (0.03%). The best efficiency on TPH removal was achieved using 0.5% SOREM™ for 60 min and its efficiency was ranged of 79.4~87.9%. Based on our preliminary study, SOREM™ will be combined with thermal desorption treatment for the contaminated soil with TPH. Key words : TPH, Diesel, Oxidation, Soil remediation, SOREM™
