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

Abstract

This paper describes removal of the pesticide 2,4-dichlorophenoxyacetic acid from aqueous solutions by sorption on aggregates formed by flocculation of micelles of the anionic surfactant sodium lauryl sulfate with aluminum sulfate. The micelles aggregate in a single floc containing all the micellar surfactant, and this floc is sufficiently consistent to be removed by filtration. This example illustrates the potential of micellar flocculation as a water treatment technique.
