The co-adsorption of aniline by complex-formation with Zn-bound and Fe-bound micelles of anionic surfactant SDS (sodium laurylsulphate) causes redox reactions. This happens both in cases where micelles become insoluble due to Fe-induced flocculation and in cases where micelles remain in solution. The interest in the phenomenon is that micellar flocculation is a means of pollutant removal by itself and synergistic effects between both flocculation and oxidation may exist.
