“…At 25.0˚C and I = 0.100 M, pK 2 and pK 3 are 7.00 and 12.8, respectively [18]. Thus at pH = 7.50 the dye is mostly in the H 2 In − and HIn 2− forms.…”

“…Thus at pH = 7.50 the dye is mostly in the H 2 In − and HIn 2− forms. It is believed that the hydroxyl group of naphthol may assist only partially in the coordination with metal ion [18]. For AVN, the oxide ion on the benzene ring and the nitrogen atom of the azo group are most probably involved in the coordination [9,12,19,20].…”

“…For CTAB, the dye molecules are incorporated in CTAB micelles, with their negative (hydroxyl) groups near the Štern layer [18]. Since the dye chelating sites are concentrated at the micelle surface, the metal ion bonds readily to two dye molecules in the vicinity of this layer.…”

“…Table 2 shows that addition of CTAB and SDS increases, whereas TX-100 lowers, β n . The lowering of pK 2 ' of the dye by CTAB [18] is expected to promote complex formation. By contrast, since TX-100 increases pK 2 ' of the dye [18], it should also lower the complex formation constant.…”

The interaction of the dye acid alizarin violet (AVN) with three transition metals was followed spectrophotometrically in water and in micellar solutions of the cationic cetyltrimethylammonium bromide (CTAB), the anionic sodium dodecyl sulfate (SDS) and the nonionic triton X-100 (TX-100). The stoichiometric ratios for the complexes of AVN with each metal ion were determined by the mole ratio and the continuous variation methods. In water, the metal to dye ratios in the complexes were 1:2,

The kinetics of the reaction of Fast Green dye (FG) with cetylpyridinum chloride was studied in alkaline medium by UV-Visible spectrophotometer. Reduction of Fast Green dye was carried out by varying the fast green dye concentration, cetylpyridinum chloride concentration and concentration of sodium hydroxide. In the present study the reduction of dye was carried out in order to reduce the color content. The interaction of dye was carried out with reducing analyte (cetylpyridinum chloride). The rate of the reaction was determined by varying the above parameters at different temperatures. It was observed that the reduction followed pseudo first-order kinetics with respect to dye, surfactant, OH -ion concentration according to the following reaction pathway.The mechanism for the photo bleaching of the dye has been proposed and well confirmed by the data simulation procedure. The activation parameters of the reaction like entropy of activation (ΔS) and free energy of activation (ΔG) showed the extremely solvated states of transient complex which was less disorderly arranged than the oxidized form of dye, whereas E a values reflects a high amount of energy required for the reduction of dye with cetylpyridinum chloride.
