The purpose of this research was to evaluate theeffect of mixed surfactant solution for removal of perchloroethyl-ene (PCE) in sandy soil. Ten different surfactant solutions wereused in column studies. Mixed surfactant solutions (anionic andy worked in the sandy soil forremoval of PCE as a result of synergism between the two types ofsurfactants. The effectiveness of the mixture of surfactants [anionicDOSL (Diphenyl Oxide Disulfonates) and nonionic Tween 60] was3538% greater than that for the anionic or nonionic surfactantalone. However, synergism between the anionic SDS (SodiumN-dodecyl Sulfate) and the anionic DOSL was not observed. Causeof the lack of synerg two anionic surfactantsis uncertain but may result from the twin head structure of DOSL.The results indicate that mixed surfactant solution (1:1 mixture ofanionic and nonionic) leaching is a promising candidate for theremediation of PCE contaminated sandy soil.
