Determination of Petroleum Oil in Soil by Fluorescence Spectrophotometry with Oscillatory Extraction by Yuan LI, Xiaoyan DUAN, Yuge SHI, Gang LI

“…The infrared spectrometry used characteristic absorption at different wavenumber to characterize the content of petroleum substances in the samples, but the response of infrared spectrometry to aromatic hydrocarbons is not sensitive.OBJECTIVESTo establish a simple pre-treatment efficiency, low detection limit and good reproducible method for determination of petroleum oil in soil.METHODSUsing n-hexane as the solvent, adsorption column as the extraction method and oscillatory as the pretreatment method, petroleum oil was extracted from soil and determined by fluorescence spectrophotometry.RESULTSUnder the optimal conditions that with 275nm as the excitation wavelength and 315nm as the emission wavelength，the extraction solvent was n-hexane and the extraction method was adsorption column, the calibration curves of petroleum oil were linear with correlation coefficients 0.999, and the detection limit was 3mg/kg. …”
