Abstract
This study investigates the remediation of crude oil-contaminated soil using thermolysis and electrokinetic techniques, focusing on their efficiency in removing contaminants and improving soil properties. Various remediation methods were tested, including thermal (T), electrokinetics (E), thermal-electrokinetics (TE), and electrokinetics-thermal (ET). Among these, the electrokinetics-thermal (ET) method demonstrated the highest efficiency, achieving a 39.4% removal of total petroleum hydrocarbons (TPH), with the lowest TPH removal of 18.9% using the thermal (T) method. The elemental analysis, conducted via X-Ray Fluorescence (XRF), indicated that oxygen and silicon were the most abundant elements, suggesting the presence of oxides and silicate minerals in the samples. The Maximum Dry Density (MDD) and Optimum Moisture Content (OMC) of the soil samples reveal moderate variations in moisture content across the treatments. The California Bearing Ratio (CBR) results indicated that the remediated soil samples, particularly those treated with thermal and electrokinetic combinations, exhibited enhanced load-bearing capacities, making them more suitable for construction applications compared to the untreated contaminated soil. The findings highlight the potential of integrated thermolysis and electrokinetics as effective remediation methods for improving the strength and environmental safety of contaminated soils.
