Surfactant enhanced aquifer remediation (SEAR) technology is a well known method in aquifer remediation of soil, solid drilling wastes and ground water from the Non Aqueous Phase Liquids (NAPLs).This investigation focus the application of surfactant enhanced aquifer remediation (SEAR) technology using modified surfactant to improve the treatment of polluted water, a new kind of surfactant was used which new various extended surfactants of the type (branched hydrocarbon chain)-(propoxyle group)-(sulfate). According to our knowledge these surfactants are not used yet to enhance the remediation of the polluted or waste water.Investigations of the phase behavior as a three components system showed the effectiveness of these surfactants in forming a two phase region of pure water and an organic phase contain the organic pollutant and the surfactant. The effect of adding a small amount of cationic hydrotropes on the formation of the desired two-phase was studied also.NMR and spectroscopic Results showed that this surfactant can be used for treatment of polluted water, and the amounts of needed surfactants to extract the organic contaminant can be determined using the three-dimensional phase behavior of the organic contaminant, water and the proposed surfactant.
