Abstract: In this work, a novel microextraction method termed polymer-coated hollow fiber microextraction (PC-HFME) was developed in combination with capillary electrophoresis (CE). Polar dihydroxylated polymethalmethacrylate polymer was coated onto a porous propylene hollow fiber membrane and used as an adsorbent and that was placed in a stirred aqueous sample solution. Tumbling of the extraction device within the sample solution facilitated extraction. The amino alcohols (2-amino-1-phenylethanol, norephedrine, alprenolol and atenolol which are β-blocker drugs), were used as model compounds to investigate the extraction performance. No organic solvent was used in this procedure. The extract was then further concentrated through on-column stacking (normal stacking mode) during CE analysis. The detection limits ranged from 0.9 to 7 ng ml-1. Relative standard deviations (n = 6) ranged from 4 to 6%. The extraction of the amino alcohols in spiked wastewater effluent (representing a complex matrix) was evaluated using the developed procedure. © 2006 Elsevier B.V. All rights reserved.
