Objective:To develop a method for analysis of alkylphenols in water by gas chromatography(GS)-mass spectrometry(MS).Methods:Water samples were extracted and enriched with OASIS HLB solid phase extraction(SPE) column,and eluted with 10% methanol-methyl tert-butyl ether.The 6 alkylphenols were determined in optimized analytical condition by GS-MS methods.Results:Average recoveries of the method were above 80% with relative standard deviation ranged from 3.5% to 5.8% in 6 tests.The correlation coefficient of s...
