Abstract
Recent studies have shown that cationic surfactants can be used to increase the organic carbon content of aquifer materials, creating enhanced sorbent zones for hydrophobic organic contaminants (HOCs) migrating in groundwater. The coupling of nonionic surfactant-enhanced solubilization of HOCs to the cationic surfactant-enhanced sorption zone concept is examined as a possible groundwater remediation scheme. The partitioning behavior of 1,2,4-trichlorobenzene (TCB) and Igepal CO 730 (CO 730, a nonionic surfactant), both singly and jointly, were determined in batch hexadecyltrimethylammonium (HDTMA, a cationic surfactant) chloride-modified aquifer material/water systems. The apparent CO 730 critical micelle concentration (cmc) was found to decrease by a factor of 17 due to nonideal mixed micelle formation in the presence of low aqueous phase HDTMA concentrations that resulted from exposure to HDTMA-modified aquifer material. A greater portion of CO 730 will be present in the micellar psuedophase (the HOC so...
