ABSTRACT:
Methods for the detection, identification and/or quantitation of halogenated hydrocarbons in aqueous samples and kits for performing the methods are provided which provide high sensitivity and can provide high selectively for individual halogenated hydrocarbons such as TCE or THMs. An additional method is provided for the sensitive determination of TTHM in an aqueous sample. These methods use a general two step procedure of (1) extracting and concentrating the halogenated hydrocarbons from the aqueous sample and (2) subjecting the concentrated halogenated hydrocarbons to a modified Fujiwara reaction to provide chromophoric products which can be analyzed by absorption spectra of the resulting mixtures.
