The method for determining six kinds of phthalates (PAEs) in white spirit by vacuum centrifugation concentration/GC-MS had been established. Samples were concentrated by vacuum centrifugation, extracted by hexane, centrifuged at 4000 r/min for 5min and tested by GC-MS with quantified by external method. The results showed that the linear ranges of six kinds of PAEs were 0.10 ~ 5.00 μg/mL (r2 > 0.992). When the scope of spiked six kinds of PAEs were 0.10 ~ 2.00 mg/kg, the average recoveries of PAEs were 88.83% -111.67%, the relative standard deviation (RSDs) and limits of detection (LODs) of the method were 4.85% ~ 11.35% and in the range of 0.02 ~ 0.05 mg/kg respectively. The method has been applied to testing of sixteen samples with satisfy results. It is easy, rapid, accurate and sensitive and meets the requirements for determining six kinds of PAEs residual in white spirit.
