Lignin phenolic structures in natural orgainc matter (NOM) were characterized by a modified version of theclassic alkali CuO oxidation method using HPLC. Vanillyl, syringyl and cinnamylfamily groups consist of three phenolic strcutres each, an aldehyde, a ketone, and acarboxylic acid. Two types of commercially-available lignin materials were analyzed bythis method for lignin monomers. One lignin material exhibited both vanillyl andsyringyl units, while the other only produced vanillyl units. Laboratory chlorination ofthe lignin polymers and the simple monomers allowed quantitative assessments of thecontribution of specific substructures to overall DBP formation. Most trihalomethaneand haloacetic acid formation appeared to be attributable to identified monomericconstituents. In contrast, observed TOX formation far exceeded that which waspredicted from the alkaline CuO fragments. Includes 17 references, tables, figures.
