“…The substituted spacer group could form hydrogen bond with water more readily and reduce the unfavorable hydrocarbon-water contact [30]. So the C 12 -4(OH) 2 -C 12 , 2Br − having two hydroxyl groups on spacer reflects greater solubilization as compared to others.…”

“…The concentration of hydrophobic compounds increases with the addition of surfactants in the water phase by solubilization or emulsification [24,25]. In recent years, a considerable amount of research has been conducted on the SER of PAHs [26][27][28][29][30][31]. Most of the work on surfactant solubilization of hydrophobic organic compounds (HOCs) has focused on the conventional monomeric anionic, cationic and nonionic surfactants.…”

“…Surfactant type not only affects the mechanism through which bioavailability is enhanced but also affects the structure of the micelles and the solubilization of components within micelles [41]. The effectiveness of micellar solubilization of hydrocarbons is depicted in terms of the molar solubilization ratio (ratio of solubility enhancement above CMC to that of surfactant concentration above CMC) and the micelle water partition coefficient (mole fraction in micelles to mole fraction in the aqueous phase at equilibrium).…”

“…For comparable hydrophobic chain lengths, nonionic surfactants typically showed higher solubilization. However, pyrene solubilization in ionic surfactants, such as sodium dodecyl sulphate (SDS, anionic), cetyltrimethyl ammonium bromide (CTAB, cationic) and dodecylethyldimethyl ammonium bromide (DDEAB, cationic), was found to be enhanced in the presence of naphthalene [41]. Such change in micelle water partition coefficients in multi-solute systems is also likely to impact SEB.…”

“…Nevertheless, PAHs exist in mixtures of many compounds at real contaminated sites. Previous reports and our recent published work demonstrated that, when cosolubilized in micellar solutions, PAH mixtures exhibit synergistic, inhibitive and negligible effects on mutual solubility compared to single solute solubilization systems (Guha et al, 1998;Bernardez and Ghoshal, 2004;Masrat et al, 2013;Liang et al, 2014;Yang et al, 2015). To date, however, there are limited reports on how the cosolubilization phenomena in aqueous phase affect the codesorption of solute mixtures from soil during the surfactantenhanced remediation process.…”
