REMEDIATION OF DIESEL CONTAMINATED SOIL BY TWEEN-20 FOAM STABILIZED BY SILICA NANOPARTICLES
Karthick, R.A. and P. Chattopadhyay.
International Journal of Chemical Engineering and Applications 8(3):194-198(2017)

To analyze the efficiency of applying nanoparticle-stabilized nonionic surfactant foams for remediation of diesel-contaminated soil, stable foams were produced from dispersions of hydrophilic and hydrophobic silica nanoparticles with the nonionic surfactant Tween-20. Tween-20 foam stabilized with 0.5 wt% hydrophobic silica nanoparticles achieved 78% maximum diesel oil removal efficiency, much higher than was obtained for Tween-20 foam stabilized with 0.5 wt% hydrophilic silica nanoparticles. The Tween-20 surfactant solution alone provided only 42% maximum oil removal efficiency. http://www.ijcea.org/vol8/655-C1004.pdf
