Abstract

The objective of this research was to elucidate the interactions among anion exchange resins, dissolved organic carbon (DOC), and inorganic anions. Model waters containing well-characterized natural organic matter (NOM) extracts were used in all experiments. The NOM extracts were isolated from three sources, and included transphilic and hydrophobic acids. The charge density of the NOM extracts, obtained by potentiometric titration, was used to perform charge balance analyses for ion exchange reactions involving DOC, bicarbonate, and chloride. Five anion exchange resins, including a magnetic ion exchange (MIEX) resin were evaluated. For all NOM extracts and anion exchange resins, the results clearly show the stoichiometric exchange of DOC and bicarbonate for chloride.
