Removal of 2,4-D from Aqueous Solutions by Micellar Flocculation with α-Olefinsulfonates

Abstract

This paper describes the use of α-olefinsulfonates (AOS) in the removal of the pesticide 2,4-dichlorophenoxyacetic acid from aqueous solutions by adsorptive micellar flocculation (AMF). The removal occurs by adsorption of the pollutant during flocculation of AOS micelles in the presence of Al3+. AOS is the second surfactant found to be susceptible to use in AMF.
