A method for the determination of phenols in environmental water with bromination derivatization and gas chromatography is described.The phenols were transformed to bromophenols and then extracted with toluene and separated by the FFAP wide bore capillary column and detected by electron capture detector(ECD).The results showed that the linear ranges were 0.06 80 μg/L for o methylphenol and p methylphenol,0.03 40 μg/L for phenol and m methylphenol.The detection limits for o methylph...
