Oily sludge was recognized as a kind of hazardous wastes,so recycling its high content of petroleum hydrocarbons can contribute to the clean environment.In this study,oily sludge was subjected to continous ultrasonic extraction with an acetone/carbon disulfide(CS2)mixture solvent.Fourier transform infrared spectroscopy(FTIRS),gas chromatography/mass spectrometry(GC/MS),and Quadrupole exactive Orbitrap mass spectrometry(QPEOTMS)were used to analyze the oil phase compounds from oily sludge.The n-alkanes ranging from Cs to C31 hydrocarbons were detected in oil phase.Compared with the analysis results of GC/MS,more heteroatom-containing compounds(HACOCs)of oil phase such as O3,O4,N2O0 and N3O0(o=0-3)could be detected by using the QPEOTMS analysis.Overall,these findings will potentially contribute to the clean and efficient utilization of oily sludge.
