Abstract: The composition of road dust samples was complex and there was no corresponding standard detection method. Based on this fact, a method mentioned by the title was proposed by combining accelerated solvent extraction (ASE) with matrix solid phase dispersion (MSPD). The road dust sample (10.0 g) was mixed well with 10.0 g of floritic silica, then put into the extraction tank (pre-adding a layer of diatomaceous earth with a thickness of about 0.5 cm), and extracted twice with a mixture of n-hexane-dichloromethane at a volume ratio of 1∶1 at 100 ℃. The extract was concentrated to about 5.0 mL, and then blown to about 1.0 mL by nitrogen. Its volume was made up to 1.0 mL with n-hexane, in which 9 phthalic acid esters (PAEs), including dimethyl phthalate (DMP), diethyl phthalate (DEP), dipropyl phthalate (DPRP), diisobutyl phthalate (DIBP), dibutyl phthalate (DBP), benzyl butyl phthalate (BBP), dicyclohexyl phthalate (DCHP), phthalate (2-ethylhexyl) ester (DEHP), and n-octyl phthalate (DNOP), were determined by gas chromatography-mass spectrometry. As shown by the results, the linear range of the standard curves of 9 PAEs was 0.1-5.0 mg·L^-1, with detection limits (3.143s) in the range of 1.10-1.39 μg·kg^-1. Test for recovery was made by the standard addition method, giving results in the range of 76.6%-107%, with RSDs(n=6) of the determined values less than 10%. This method was applied to analysis of the actual samples, with higher detection amounts of 8.06-233 μg·kg^-1 for DIBP, 23.9-3 148 μg·kg^-1 for DBP, and 16.5-4 106 μg·kg^-1 for DEHP, respectively.
