Dye–micelle aggregate formation for effective photobleaching

Incorporation of six different (three cationic: MB, CV, AO and three anionic: RB, E and Fl) dye molecules in three different micellar environments has been examined critically for photobleaching of the dye–micelle aggregates. Micellar media have been found to influence the rate of decolorization which has been explained considering electrostatic, hydrophobic and charge transfer interactions. Further rate enhancement of colour bleaching was observed with Se nanoparticles. In depth, kinetic studies have been carried out to realize the interaction of the dyes with micelles. Kinetic studies have revealed that the reaction is first order with respect to dye concentration.
