Chlorination of fulvic acid isolated from a natural surface water produces a variety of C1 to C4 aliphatic acids in addition to chloroform. Yields of the four principal reaction products, trichloroacetic acid, chloroform, dichloroacetic acid, and dichlorosuccinic acid are approximately 14 wt % of starting organic material and account for 53% of the total organic halogen. No halogenated aromatic products were identified. This appears to be the first reported quantitation of unambiguously identified major chlorination products, which accounts for the majority of the total organic halogen. An isotope dilution GC/MS method for the determination of aqueous trichloroacetic acid is also described. (Copyright (c) 1983 American Chemical Society.)
