In the present work, the surface properties of mixed binary surfactants containing sodium dodecylbenzene sulfate (SDBS) and Tween 80 (TW80) surfactants in aqueous solutions were studied at temperature 293 K using surface tension measurements. The critical micelle concentration (cmc) magnitude for both individual surfactants and their mixtures were established the obtained results revealed that the magnitude of cmc of the mixtures are less than the magnitude of individual surfactants and decrease with the increase in Tween 80 percent in solution which indicate the nonideal mixing of the two surfactants. The values of molecular interaction parameters and the mole fraction of surfactants in the micelle (X1) were calculated on the basis of Rubingh's model and showed that the interaction parameter is always negative but at 0.9 mole fraction of TW80 surfactant (α 1 ) is positive.

“…We are using a spectrophotometric technique and used the modified Benesi-Hildebrand equation for the first time to calculate the binding constant of methyl red in the presence of DTAB/ethanol/water systems as such concept was used to calculate the binding parameters(binding constant and standard Gibb's free energy of binding) for dyes (methylene blue and methyl orange) absorbance in DTAB-SDS mixed surfactant by absorption technique in an aqueous medium without using critical micelle concentration (CMC) values. 22…”

The interaction of azo dye methyl red (MR) with dodecyl trimethyl ammonium bromide (DTAB) has been studied spectrophotometrically through azo-hydrazone tautomeric behavior of MR for a series of the ethanol-water system (0.1, 0.2, 0.3 and 0.4 volume fractions of ethanol) at room temperature. Critical micelle concentration was determined using the conductometric technique with increased ethanol volume influenced by solvent polarity and architectural flexibility of methyl red. The azo form of methyl red brings electrostatic interaction with cationic surfactant through the adsorption phenomenon. The binding parameters were calculated with the aid of a modified Benesi-Hildebrand equation.

An attempt has been carried out to prepare vanadia loaded TiO2 supported on MCM-41(V-TiO2/MCM-41) nanostructured photocatalysts using different surfactants. The surfactants used in the photocatalysts synthesis were dodecyl-trimethyl-ammonium bromide (DTAB), hexadecyl-trimethyl-ammonium bromide (CTAB) and octadecyl-trimethyl-ammonium bromide (STAB) which have varied carbon chains. The effect of crystallinity, surface area and porosity of the MCM-41 support on the physical-chemical properties of synthesized photocatalysts of vanadia loaded TiO2/MCM-41 and their photocatalytic performance were investigated. X-ray diffraction (XRD) patterns showed that the crystallinity of vanadia-TiO2/MCM-41 decreased with increasing of carbon-chain number of the surfactant used. Both surface area and pore volume of V-TiO2 increased significantly from 16.2 m2/g and 0.034 cm3/g to 864.3 m2/g and 0.618 cm3/g, respectively, after being loaded on MCM-41 support which was prepared using CTAB. It was demonstrated that all the V loaded TiO2/MCM-41 materials exhibited remarkable improvement in photocatalytic degradation of methylene blue (MB) under the irradiation of visible light as compared to that of bare TiO2 and V-TiO2. Among these materials, V-TiO2/MCM-41 which was synthesized using CTAB appeared to be the best photocatalyst with 57% of MB removal under visible light irradiation.
