AB  - This work proposes for the first time the use of a three phase hollow fiber 
      liquid phase microextraction (HF-LPME) procedure for the simultaneous extraction, 
      and the later HPLC determination, of some phenol substituting compounds (alkyl-, 
      chloro- and nitrophenols) that are considered as highly toxic compounds and/or 
      endocrine disrupting ones. The substances studied include four chlorophenols 
      (CPs): 2,4-dichlorophenol (2,4-DCP), 2,5-dichlorophenol (2,5-DCP), 
      2,6-dichlorophenol (2,6-DCP) and pentachlorophenol (PCP), three nitrophenols 
      (NPs): 2,4-dinitrophenol (2,4-DNP), 2,5-dinitrophenol (2,5-DNP) and 
      2,6-dinitriphenol (2,6-DNP) and two alkylphenols (APs): tert butylphenol (TBP) 
      and sec butylphenol (SBP). The extraction was carried out through a dihexyl ether 
      liquid membrane supported on an Accurel((R)) Q3/2 polypropylene hollow fiber. 
      Optimum pH for donor and acceptor phases and extraction time were established. 
      The enrichment (preconcentration) factors obtained were between 30 and 700 that 
      allows detection limits between 140 and 290 pg mL(-1). The method was 
      successfully applied to the determination of the compounds in environmental water 
      samples, including urban wastewaters.
