A method was developed for the extraction of phthalic acid esters (PAEs) from bottled water. Surface-functionalized magnetic particles (MPs) were used as adsorbent of magnetic solid-phase extraction (MSPE). The MPs were prepared by using both polydimethylsiloxane and multiwalled carbon nanotubes. By coupling the developed MSPE with GC–MS instrument, a reliable, sensitive and cost-effective method for the simultaneous determination of six main PAEs including dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), butyl benzyl phthalate, di- n -octyl phthalate and bis(2-ethylhexyl) phthalate (DEHP) was developed. Under optimized conditions, the LODs and limits of quantification were in the range of 0.01–0.025 and 0.025–0.05 µg/L, respectively. The calibration curves were linear ( r  2  ≥ 0 . 992) over the concentration ranges from 0.05 to 20 µg/L. Based on the intra- and interday precision values with overall RSD ≤ 12.40%, the method reproducibility was adequate. The recovery values of the six PAEs ranged from 91.5 to 97.8% with the RSDs &lt;10.64%. Finally, the developed method was successfully applied to determine PAEs in bottled water samples. DMP, DEP, DBP and DEHP were detected in most of the samples. Taken together, the developed MSPE–GC–MS method provides a new option for the determination of PAEs in aqueous samples.
