摘要：
Difficulties detected in the determination of the diethylhexylphthalate (DEHP) at trace levels by gas chromatography-mass spectrometry (GC-MS) using SPME, due to its ubiquitous distribution in the environment has been overcome and a new method for the determination of DEHP in drinking water has been proposed. The method is based on solid phase microextraction (SPME) coupled to high-performance liquid chromatography (HPLC). Detection was carried out spectrophotometrically. Calibration graph was linear in the range 10-110 mu g/L with a regression coefficient of r(2) = 0.998 and a detection limit of 0.6 mu g/L. The relative standard deviation was 5 and 2% (n = 4) for chromatographic areas and retention times, respectively. The usefulness of the SPME-HPLC technique was confirmed. (c) 2005 Elsevier B.V.
