【Abstract】 A new method for the determination of phenols in waste water has been established by coupling solid phase microextraction (SPME) with gas chromatography mass spectrometry. The operating conditions of SPME such as extraction time, stirring rate, ionic strength, pH and adsorption time were studied. A manual SPME holder with 65 μm polyolimethyl siloxane/divinyl benzene coated was used to extract phenols from water with satisfactory results.更多还原
