| Abstract: | Carbon tetrachloride is taken as extraction agent for extracting the oils in water. The extract is adsorbed with silicic acid magnesium. After the polar substances like animal and vegetable oils are eliminated, the determination of the petroleum oils are made by infrared spectrophotometry. 20 mL volume of the extraction agent is suitable. The best analysis wavelength selected is （3.28±0.01） μ m. This method has low analysis cost and high precision and accuracy. The RSD （n=10） is equal or greater than 2.4% and the relative error is equal or lesser than 3.0%. |
