Critical Micelle Concentration (CMC) is the key point for surface chemistry as well as chemist and systematic data collection and day-to-day development in this regard is very essential. Hence, we have analyzed the CMC of surfactant, mixed surfactant and polymer at room temperature (28C), with the change in surfactant, mixed surfactant and polymer concentration CMC values were observed by two m...

Batch and column experiments were conducted to evaluate the efficiency of a clinoptilolite zeolite as an inexpensive sorbent material to remove cationic surfactant from water. With an initial surfactant concentration greater than its critical micelle concentration, the removal of surfactant is achieved by admicellar sorption onto the zeolite surface. Although the sorption capacity of hexadecylt...

Surface activity and micelle formation of alkylguanidinium chlorides containing 10, 12, 14 and 16 carbon atoms in the hydrophobic tail were studied by combining conductivity and surface tension measurements with isothermal titration calorimetry. The purity of the resulting surfactants, their temperatures of Cr→LC and LC→I transitions, as well as their propensity of forming birefringent phases, ...

This review incorporates a large number of chromatographic systems modified by the surfactants. A large number of solvent systems and stationary phases are summarized in this paper. Three different kinds of surfactants (anionic, cationic, and nonionic) are used as modifiers for stationary phases as well as solvent systems. Surfactants are used at all the three different concentration levels (be...

water soluble chitosan oligosaccharide (cho) was hydrophobically modified with camptothecin (cpt) in different molar ratios of cpt, and characterized by ft-ir and 1 h-nmr spectroscopy. nanomicelles prepared by these copolymers were analyzed for size, zeta, and length of time they remain stable. the critical micelle concentration (cmc) and dissociation of micelles at physiological ph and acidic ...
