Possibilities of Using the Surface Concentration of Surfactant Mixtures for Wastewater Treatment

详细

Correlation between the manifestation of synergic action of surfactants in the process of their adsorption at the binary solution–air interface and the efficiency of the surface concentration of surfactants has been found. The use of the parameter of intermolecular interaction of surfactants in mixed adsorption layers is shown to be expedient for predicting the surface concentration of surfactants during their extraction from multicomponent aqueous solutions and wastewater. The possibility of intensifying the flotation extraction of some ionogenic surfactants from aqueous solutions in the presence of Tweens has been confirmed.
