Gemini　surfactants,　an　innovative　class　of　amphiphilic　molecules,　are　of　increasingly　scientific　interest　due　in　part　to　their　effectiveness　in　soil/water　remediation.　This　study　was　carried　out　to　investigate　the　overall　partitioning　of　three　representative　polycyclic　aromatic　hydrocarbons　(PAHs)　in　the　soil-water-surfactant　system　which　takes　into　consideration　the　soil-sorbed　cationic　Gemini　surfactant,　presence　of　Gemini　micelles,　and　related　developed　coefficients.　The　results　indicated　that　the　adsorption　of　Gemini　surfactants　onto　soil　particles　through　both　cation　exchange　and　hydrophobic　interaction　contribute　to　the　bi　or　multilayer　formation.　The　sorbed　C12-3-12　studied　herein,　is　a　highly　effective　partitioning　media　for　PAHs　to　adsorb　onto　the　soil　phase　from　the　aqueous　phase　and　thus,　can　be　considered　as　a　good　adjuvant　for　an　enhanced　sorption　zone.　The　partitioning　behavior　of　PAHs　in　the　soil-water-Gemini　surfactant　has　a　strong　relationship　with　their　K-ow.　The　experimental　results　from　this　research　will　be　used　to　gain　an　understanding　of　the　effect　of　cationic　Gemini　surfactant　on　the　distribution　of　HOCs　in　a　soil-water　system　and　provide　some　fundamental　and　valuable　information　in　remediation　of　contaminated　soils　and　waters.
