Abstract

A new method for the determination of phenol residues in honey has been established by coupling headspace solid-phase microextraction(SPME) with gas chromatography-mass spectrometry.Extraction conditions,such as fibers for SPME,extraction temperature,extraction time and desorption time were optimized.The results showed that a SPME fiber coated with 85 μm polyacrylate was used to extract phenol from honey with satisfactory results.The linear ranges of phenol were from 0.5 to 1000 ng/g.The detection limit and the relative standard deviation were 0.1 ng/g and 3.33%(S/N=9),respectively.The recoveries were from 85.79% to 99.35%.
