Abstract

Solid phase microextraction(SPME) with <TEX>$85{\mu}m$</TEX>-polyacrylate (PA) and <TEX>$100{\mu}m$</TEX>-polydimethylsiloxane(PDMS) fibers, coupled to gas chromatography-mass spectrometry was used to determine 1,2-dibromo-3-chloropropane(DBCP) and n-butylbenzene in water. The conditions affecting the SPME process(i.e, extraction time, injection length, injection temperature, desorption time and temperature) were optimized. The linearity of the calibration curve (correlation coefficient, R) was over 0.99 and the limits of detection of the method were between 1.5 and <TEX>$10.8{\mu}g/L$</TEX>. Repeatability of the method was between 10.4 and 14.4 %.
