IMPROVED SOLID PHASE MICROEXTRACTION FIBER, PREPARATION METHOD THEREOF AND METHOD FOR ANALYZING ALKYLPHENOL AND BISPHENOL-A IN WATER SAMPLE BY USING THE SAME

摘要

PURPOSE: Provided is an improved solid phase microextraction(SPME) fiber performing an extraction, concentration, and derivatization simultaneously thereon. A method for analyzing an alkylphenol and a bisphenol-A in a water sample by using the SPME fiber is also provided. CONSTITUTION: The SPME fiber is produced by soaking a SPME fiber in a mixture, comprising bis(trimethyl silyl)trifluoro acetamide(BSTFA) and trimethyl chloro silane(TMCS) in the weight ratio of 100:1, for 30min to 2hrs to absorb the BSTFA into the SPME fiber. And the method for analyzing the alkylphenol and the bisphenol-A comprises the steps of: bring the SPME fiber into contact with the water sample to absorb the alkylphenol and the bisphenol-A into the fiber; separating the fiber and then analyzing by using a gas chromatography/mass spectrometer(GC/MS).
