dc.description.abstractHumic acids (HA) can affect the partitioning of organic contaminants between aqueous and sediment phases by complexation in solution and adsorption of the contaminant-HA complex to a mineral surface. The objective of this work was to elucidate these and other mechanisms, using 14C-radiolabeled 2,2' ,4,4'-tetrachlorobiphenyl (TeCB), a filtered humic acid preparation, and two natural kaolinites (KGA). The binary interactions, TeCB with KGA, HA with KGA, and TeCB with HA, were studied experimentally at 25 °C and pH 6.9. Isotherms were measured for the TeCB-HA-KGA multicomponent system to evaluate adsorption partition coefficients. The data were fitted satisfactorily, within estimated limits of uncertainty, by a model that assumes noncompetitive TeCB and HA adsorption and the same binding constant between free TeCB and dissolved or adsorbed HAen_US
