The objective of this research was to elucidate the interactions among anion exchangeresins, dissolved organic carbon (DOC), and inorganic anions. Model waters containingwell-characterized natural organic matter (NOM) extracts were used in all experiments.The NOM extracts were isolated from three sources, and included transphilic andhydrophobic acids. The charge density of the NOM extracts, obtained by potentiometrictitration, was used to perform charge balance analyses for ion exchange reactionsinvolving DOC, bicarbonate, and chloride. Five anion exchange resins, including amagnetic ion exchange (MIEX) resin were evaluated. For all NOM extracts and anionexchange resins, the results clearly show the stoichiometric exchange of DOC andbicarbonate for chloride. Includes 17 references, tables, figures.
