Petroleum Hydrocarbons Extraction Efficiency of Carbon Tetrachloride and Trichlorotrifluoroethane: A Comparative Study

摘要

Petroleum hydrocarbons (PHC) contaminated water samples, prepared in laboratory, were analyzed using infrared spectroscopy to compare PHC extraction efficiency of carbon tetrachloride (CCl_4) and trichlorotrifluoroethane (C_2Cl_3F_3) solvents. The comparison of the results illustrated that PHC extraction efficiency of CCl_4 was greater than C_2Cl_3F_3. The higher extraction efficiency of CCl_4 was ascribed to its more non-polar nature and higher polarity index. This study supported the selection and use of CCl_4 for extraction and quantification of PHC of groundwater samples of the projects carried out in the department.
