Ethyl acetate showed higher extraction efficiency than acetone and isopropanol as elution solvent [81] DEP, DPP, DBP, DIPP, DNPP, BBP, DCHP, DEHP, DNOP, DINP, DIDP and DEHA Mineral, tap, pond and waste waters (25 mL adjusted at pH 6) m-dSPE using 60 mg Fe₃O₄-PDA under agitation for 1 min, a magnet was used for decantation, and elution with 6 mL dichloromethane by agitation for 30 s GC-MS/MS 0.009–0.02 μg/L 71–120% at 0.5 and 5 μg/L One sample of each water were analyzed and residues of DEP and DBP were found at levels from 0.36 ± 0.46 to 4.20 ± 0.52 μg/L in the mineral, tap and waste waters Dichloromethane showed higher extraction efficiency than acetone, MeOH and ACN as elution solvent [22] DMP, DEP, BBP, and DBP Carbonated, mineral and soda waters (25 mL) m-dSPE using 30 mg poly(1-vinyl-3-butylimidazolium bromide)-PS m-NPs under vortex for 2.5 min, a magnet was used for decantation, and elution with 7 mL ACN by sonication HPLC-DAD 0.017-0.047 μg/L 77.8-102.1% at 2 and 20 μg/L One sample of each water were analyzed and residues of DEP were found at 25.8 and 15.5 μg/L in the carbonate and soda waters, respectively ACN showed higher extraction efficiency than acetone, petroleum ether and MeOH as elution solvent [82] DMP, DEP, DAP, DIBP, and DBP Tap and well waters (5 mL plus 15% w/v NaCl) m-dSPE using 15 mg Fe₃O₄-MIL-101(Cr) MOF under agitation for 20 min, a magnet was used for decantation, and elution with 1 mL hexane/acetone (1:1 v/v) by vortex for 3 min GC-MS 0.3–0.5 μg/L 90.1–106.7% at 5 and 50 μg/L One sample of each water were analyzed and no residues were detected The use of Fe₃O₄-MIL-101(Cr) MOF showed higher enrichment capacity than Fe₃O₄ and MIL-101(Cr) MOF separately.
