摘要: The aggregation induced by Alizarin Yellow R (AYR) in the cationic surfactant, cetyltrimethylammonium bromide (CTAB), was investigated measuring their UV–visible absorption spectra. Conductance measurements as a function of surfactant concentration below and above critical micelle (CMC) were studied. CTAB takes place at far its normal CMC presence AYR. Both hydrophobic electrostatic interactions affect process aqueous solution. dye effect on noted specific conductivity method well. AYR–CTAB binding constant (Ks) water–micelle partition co-efficient (Kx) quantified with help mathematical models employed to determine partitioning organic additives micellar phase. number molecules per estimated particular concentrations CMC, during this study.
