  • Title: Synergism in the desorption of polycyclic aromatic hydrocarbons from soil models by mixed surfactant solutions.
    Author: Sales PS, Fernández MA.
    Journal: Environ Sci Pollut Res Int; 2016 May; 23(10):10158-64. PubMed ID: 26873826.
    Abstract:
    This study investigates the effect of a mixed surfactant system on the desorption of polycyclic aromatic hydrocarbons (PAHs) from soil model systems. The interaction of a non-ionic surfactant, Tween 80, and an anionic one, sodium laurate, forming mixed micelles, produces several beneficial effects, including reduction of adsorption onto solid of the non-ionic surfactant, decrease in the precipitation of the fatty acid salt, and synergism to solubilize PAHs from solids compared with individual surfactants.
