A headspace
solid-phase microextraction (HS-SPME) method is developed for the determination
of styrene in drinking water. Gas chromatography (GC)–mass spectrometry
is utilized for qualitative analysis. A manual SPME holder with 85-µm
polyacrylate coating is used to extract the styrene from water, which is determined
to have good linearity (correlation coefficient r = 0.9999 for 1.00–100.00
µg/L range), a relative standard deviation of 1.9%, and a detection limit
of 0.30 µg/L. This method is compared with a classical headspace GC method.
