Head Space-Solid Phase Micro Extraction-Gas Chromatography/Mass Spectrometry
(HS-SPME-GC/MS) was optimized for the determination of 3 phenol compounds(phenol,
2,4-dimethylphenol and pentachlorophenol) in wastewater samples. Analytes were
acetylated in situ, and HS-SPME was performed. Among the five SPME fibers
compared, the PDMS/DVB fiber was found to be the most sensitive when used
HS-SPME/GC/MS was used. The following optimum SPME parameters were selected :
choice of SPME fiber(PDMS/DVB), salt effect(NaCl 3 g), headspace incubation
temperature(40℃), headspace adsorption time(60 min). The calibration curve of the
phenol compounds in the range of 0.01~2.0 μg/L showed good linearity with the
correlation coefficient of r2=0.99 and the recoveries by this method were 74.4~127.8%.
