Effects of cationic and anionic surfactants on the adsorption of toluidine blue onto fly ash

Abstract

The adsorption of cationic dye toluidine blue (TB) onto fly ash has been studied from aqueous solution, in the presence of cationic surfactant cetyl pyridinium chloride (CPC) and anionic surfactant sodium dodecyl sulfate (SDS) at three different temperatures.
