      Solid-Phase Extraction of Phthalates.

AB  - Poly(phenyl-(4-(6-thiophen-3-yl-hexyloxy)-benzylidene)-amine) (P3TArH) was 
      successfully synthesized and coated on the surface of Fe(3)O(4) magnetic 
      nanoparticles (MNPs). The nanocomposites were characterized by Fourier transform 
      infra-red (FTIR), X-ray diffractometry (XRD), Brunauer-Emmett-Teller (BET) 
      surface area analysis, analyzer transmission electron microscopy (TEM) and 
      vibrating sample magnetometry (VSM). P3TArH-coated MNPs (MNP@P3TArH) showed 
      higher capabilities for the extraction of commonly-used phthalates and were 
      optimized for the magnetic-solid phase extraction (MSPE) of environmental 
      samples. Separation and determination of the extracted phthalates, namely 
      dimethyl phthalate (DMP), diethyl phthalate (DEP), dipropyl phthalate (DPP), 
      dibutyl phthalate (DBP), butyl benzyl phthalate (BBP), dicyclohexyl phthalate 
      (DCP), di-ethylhexyl phthalate (DEHP) and di-n-octyl phthalate (DNOP), were 
      conducted by a gas chromatography-flame ionization detector (GC-FID). The best 
      working conditions were as follows; sample at pH 7, 30 min extraction time, ethyl 
      acetate as the elution solvent, 500-microL elution solvent volumes, 10 min desorption 
      time, 10-mg adsorbent dosage, 20-mL sample loading volume and 15 g.L(-1) 
      concentration of NaCl. Under the optimized conditions, the analytical 
      performances were determined with a linear range of 0.1(-)50 microg.L(-1) and a limit 
      of detection at 0.08(-)0.468 microg.L(-1) for all of the analytes studied. The 
      intra-day (n = 7) and inter-day (n = 3) relative standard deviations (RSD%) of 
      three replicates were each demonstrated in the range of 3.7(-)4.9 and 3.0(-)5.0, 
      respectively. The steadiness and reusability studies suggested that the 
      MNP@P3TArH could be used up to five cycles. The proposed method was executed for 
      the analysis of real water samples, namely commercial bottled mineral water and 
      bottled fresh milk, whereby recoveries in the range of 68%(-)101% and RSD% lower 
      than 7.7 were attained.
