Περίληψη | A simple and efficient liquid-phase microextraction (LPME) technique using a hollow-fibre membrane, in conjunction
with gas chromatography–mass spectrometry has been developed for the extraction and analysis of six phthalate esters in
water samples. Parameters such as extraction solvent, agitation of the sample, salt addition and extraction time were
controlled and optimised. The developed protocol was found to yield a linear calibration curve in the concentration range
21 21 from 0.02 to 10 mg l for most target analytes and the limits of detection were in the low mg l level, ranging between
21 0.005 and 0.1 mg l . The repeatability of the method varied between 4% and 11%. Under the present experimental
conditions, the performance of the method was found comparable to that of solid-phase microextraction (SPME). The
advantage of the proposed method over SPME was that it eliminated carry-over of analytes between runs. The applicability
of the developed hollow-fibre LPME method and SPME was demonstrated for real water samples. The ability of both
microextraction methods to concentrate many organic analytes was demonstrated as both methods allowed the confirmation
of the presence of an extra contaminant (ethyl p-ethoxybenzoate) in bottled mineral water samples. | en |
