摘要： As the hazardous wastes, recycling the high petroleum hydrocarbon content of oily sludge contributes to clean environment. In this study, Oily sludge was subjected to ultrasonic extraction sequentially with acetone/carbon disulfide mixture solvent. Fourier transform infrared spectroscopy (FTIRS), Gas chromatography/mass spectrometry (GC/MS) and Quadrupole exactive orbitrap mass spectrometry (QPEOTMS) were used to analyze oil phase compounds of oily sludge. The n-alkanes detected in oil phase ranging from C8 to C31. Compared with analysis results of GC/MS, more heteroatom-containing compounds of oil phase such as O3, O4, N2Oo and N3Oo (o=0-3) could be detected in the analysis of QPEOTMS. Overall, these findings will potentially contributed to the clean and efficient utilization of oliy sludge wastes.
