    Abstract

    The precision and accuracy of acidification followed by Soxhlet extraction with trichlorotrifluoroethane to estimate the oil and grease content of oil-contaminated soils was determined. The amounts of oil and grease were determined gravimetrically after solvent extraction. Stock oil-soil mixtures prepared with vegetable oil, No. 2 fuel oil, No. 6 fuel oil, motor oil, and an oily waste were analyzed. The coefficient of variation for all oil-soil mixtures analyzed never exceeded 4%. The percentage of recovery varied from 68% for No. 2 fuel oil to 102% for motor oil. The results indicate that this method is precise and results in reasonable recoveries when used to measure the oils tested.
