Sorption of ethylhexadecyldimethylammonium (EHDDMA+), a large organic cation, and three neutral organic compounds (NOC's) on two low organic carbon aquifer materials was studied using a soil batch equilibration technique. EHDDMA+ competed effectively with metals for exchange sites and EHDDMA+ sorption was accompanied by an equimolar charge desorption of metals. NOC's sorption on the aquifer materials was low (K less than or = 0.22) which was consistent with the sorbent's low organic carbon content. However, EHDDMA+ sorption increased toluene sorption by two orders of magnitude. The enhanced toluene sorption was due to the hydrophobic surface provided by the hydrocarbon moiety of sorbed EHDDMA+.
