Abstract

A homologous series of alkybenzenes was sorbed to well-characterized mineral oxides in batch experiments to elucidate mechanisms of sorption in the absence of natural organic matter. Sorbed concentration was determined by measuring the headspace concentration in a closed vessel partially filled with a water/alkylbenzene/solid slurry. Partitioning of dissolved alkylbenzenes to sorbed alkylbenzenes was observed at high sorbed concentrations. At low sorbed concentrations, the mechanism was surface adsorption limited by the surface area of the solids. Enhancement of the adsorption of individual compounds was observed when alkylbenzenes were sorbed as a mixture.
