Study of Ultraviolet Spectrophotometer for Rapid Analysis of Oil Content in the Oil-Contaminated Soil

Abstract:

Oil soil samples were extracted using cyclohexane, petroleum ether and chloroformion by the ultrasonic method. The feasibility of the ultraviolet spectrophotometric method for rapid analysis of the oil content in the oil-contaminated soil was explored. The result indicates that compared with other test methodsultraviolet spectrophotometry can be a simple, quick and steady detection method of oil content in the oil-contaminated soil. The method of oil material extracted by cyclohexane is high efficiency and stable. When the temperature was between room temperature and 40°C, ultrasonic extraction time is 15 min, and the extraction efficiency turned out to be stable (greater than 94%) when solvent dosage exceeded 40mL. Two stages extraction could achieve the best effect with the extraction dosage of 20 mL for each stage.
