“…It is seen that both the conductivity and CMC of SDS decrease with the addition of methylene blue because the dye has a positive charge which reduces the mutual repulsion within the anionic moiety of SDS [61] by binding with the micellar aggregates at the surface [34].…”

The surface activity and the process of micellization of sodium dodecyl sulfate (SDS) with methylene blue (MB) in a methanol-water mixed solvent system were investigated by tensiometry and conductometry at 298.15 K. The measurements of surface tension and conductivity of SDS-MB complex were carried up to 0.3 volume fractions of methanol because the resulting complex appeared turbid above 0.3 volume fractions of methanol. The critical micelle concentration (CMC) of the SDS was determined from both tensiometry and conductometry. The CMC of SDS increased with the increasing volume fraction of methanol due to the inclusion of methanol in the micelles and decreased in the presence of methylene blue due to the reduction of electrostatic repulsion within the anionic moiety of SDS by the positive charge of the added dye. Different properties like surface excess concentration Γ max , minimum surface area A min , Gibbs free energy of micellization Δ G m o , surface pressure ( π CMC ), efficiency of a surfactant ( p C 20 ), packing parameter P , and standard free energy interfacial adsorption Δ G ads o of SDS in the absence/presence of MB were calculated. On the basis of Δ G m o values, it was noticed that the increasing volume fraction of methanol disfavors the micellization of SDS, while the presence of MB increased the efficiency of SDS making the micellization process more spontaneous.

“…potentiometry [5], or conductometry [6]. The most often used method to investigate dye -surfactant interactions at a concentration below and above CMC is spectrophotometry [7][8][9][10]. Traditionally, the CMC can be determined by observing sharp changes in a number of physical properties such as surface tension [11], turbidity [12], UV-Vis absorbance [3,13,14], and classically electrical conductivity [15].…”

The critical micelle concentration (CMC) for a series of cationic surfactants N-Alkyltrimethylammonium i.e. (C n TAC, n=12,14,16,18) have been determined by electrical conductivity and surface tension methods. The interaction of anionic dye Eriochrome Black T (EBT) with cetyl-trimethylammonium chloride and cetylpyridinium chloride (CPC) has been investigated spectrophotometrically. The binding constant (K b ) and the surface excess (Γ) were calculated. The results show that with increasing the surfactants alkyl chain lengths, CMC and minimum area (A min ) decreases, while the surface excess concentrations increase. It has been found that the binding constant of CPC is double -fold that than of the binding constant of cetyl-trimethylammonium chloride (C 16 TAC).
