Ultrasonic-assistant Dispersive Liquid-liquid Microextraction Based on Solidification of Floating Organic Droplet Method for Quick Determination of Polycyclic Aromatic Hydrocarbons in Soils

摘要：

　　An ultrasound-assisted dispersive liquid-liquid micro-extraction method based on solidification of floating organic drop (UAE/DLLME/SFO) was established for the determination of PAHs in soils.Dichloromethane was used as solvent for the analytes in the soil by ultrasonic assistant extraction (UAE), the solvent was purified and concentrated by silica gel column chromatography and nitrogen flowing concentrator, respectively.The recoveries of the method were in the range 46.22-101.86%, and the relative standard deviations (RSD) were 3.03-7.80%.The linear range was 0.02-0.4mg/kg (0.02-0.5mg/kg) , and the limit of detection (LOD) was 0.17-29.13μg/kg.The method was applied to the real soil samples around wells of an oilfield; the relative recoveries of the ANY, ANA, FLU, PHE, ANT, FLT, PYR, BaA were 47.12-116.96%, while the recoveries of NAP, CHR, BbF, BkF, BaP, DBA, BPE, IPY were 17.75-63.29%.
