AB  - A method was established for the simultaneous determination of some phthalic acid 
      esters, namely, dimethyl phthalate (DMP), diethyl phthalate (DEP), dipropyl 
      phthalate (DPrP), dibutyl phthalate (DBP), diamyl phthalate (DAP), dihexyl 
      phthalate (DHP), benzyln-butyl phthalate (BBP), di-(2-ethylhexyl) phthalate 
      (DEHP), dicyclohexyl phthalate (DCHP), di-n-octyl phthalate (DNOP), diisononyl 
      phthalate (DINP) and diisodecyl phthalate (DIDP) in textiles by solid phase 
      extraction (SPE) coupled with gas chromatography (GC). The phthalic acid esters 
      in textiles were extracted by Soxhlet extraction with hexane, the extracts were 
      then cleaned up and enriched by a strong anion exchange (SAX) SPE cartridge. The 
      parameters affecting the purification efficiency of SPE cartridge, such as 
      solvent conditioning, rinsing, and elution, were studied. Conditioning with 5 mL 
      hexane and rinsing with 3 mL isooctane were proved to be the optimal conditions. 
      Of the several solvent ratios (ethylacetate in hexane) used for selective elution 
      of phthalic acid esters from the SAX SPE cartridge, the 15% (v/v) content for 
      ethylacetate in hexane gave the best result. Under the optimized conditions, the 
      recoveries of phthalic acid esters for spiked standards (n=7) were 86.3%-102.7%, 
      and the relative standard deviations (RSDs) were less than 5%. In this method the 
      detection limits for DMP, DEP, DPrP, DBP, DAP, BBP, DCHP, DEHP, DNOP were all 
      below 1 mg/kg, and the detection limits for DINP and DIDP were 1.74 mg/kg and 
      1.55 mg/kg respectively. This SPE-GC method is sensitive, accurate and suitable 
      for the analysis of phthalate environmental hormones in textiles.
