摘要
[Objective] This paper aimed to study the rapid identification method of hazardous wastes from illegal oil refining,and provide a new theoretical basis and practical basis for shortening the appraisal cycle and reducing the cost of identification.[Method] The identified substance and the qualified oil products were diluted by carbon disulfide with a ratio of 1∶100 for the gas chromatographic analysis.According to the corresponding national standard,the oil change indexes,such as the moisture content,viscosity,acid value and mechanical impurities of the identified substance,were measured.[Result] By the comparison between the gas chromatogram spectrograms of the identified substance and the qualified oil,it is found that the main component of the identified substance was the mineral oils.And the test results of oil change index showed that the mineral oil was unqualified.[Conclusion] This method was of great significance to save the cost of appraisal and improve the efficiency of case handling.
