Abstract: |
A rapid,sensitive and accurate method was developed for the simultaneous determination of 6 kinds of phthalic acid esters(PAEs)in wine samples by dispersive magnetic solid phase extraction coupled with high performance liquid chromatography(dMSPE/HPLC).The wine samples were concentrated with polystyrene nano-magnetic materials,then separated on a C8 analytical column(250 mm×4.6 mm×5 μm) using methanol-water as mobile phase by gradient elution,and detected at 230 nm via UV detector.The results showed that,under the optimal condition,good linearities for the target PAEs were obtained between 2 ng/L and 500 ng/L with correlation coefficients(r2) not less than 0.997 9.The spiked recoveries were between 85.2% and 101.2% with relative standard deviations(RSDs) of 0.8%-9.2%.The limits of detection(LODs) were in the range of 0.22-4.5 ng/L and the limits of quantitation(LOQs) were 1.2-10 ng/L.The developed method could be applied in the routine analyses on PAEs in wine samples. |
