| Abstract: | An analytical method of trace organic impurities in industrial phenol was developed by solid-phase microextraction combined with gas chromatography-mass spectrometry. The method is simple, rapid and sensitive for the determination of the impurities in the phenol. By observation of experiments the optimization conditions were found as follows： the micro-extracter was a coated fiber with polydimethyl siloxane of 100 μm, the extraction time for 10 min, the temperature at 20 ℃, and the desorption time for 30 seconds under 240 ℃. |
