چکیده

A fluorescence probe study on micellization of the binary surfactant system formed by n-octyl-d-thioglucopyranoside (OTG) and sodium dodecyl sulphate (SDS) in 0.1 M NaCl aqueous solutions has been carried out. The CMC experimental data, as obtained by the pyrene 1:3 ratio method, have been analyzed in the context of the pseudophase separation model. The interaction parameter (β12) determined by using the regular solution theory (RST) was found to be negative and independent on the solution composition. In addition, the experimental data o e m o w c t e m i ©

Self-Assembly, Surface Activity and Structure of n-Octyl-β-D-thioglucopyranoside in Ethylene Glycol-Water Mixtures

The effect of the addition of ethylene glycol (EG) on the interfacial adsorption and micellar properties of the alkylglucoside surfactant n-octyl-β-D-thioglucopyranoside (OTG) has been investigated. Critical micelle concentrations (cmc) upon EG addition were obtained by both surface tension measurements and the pyrene 1:3 ratio method. A systematic increase in the cmc induced by the presence of...

Interaction Studies of Sodium N-Dodecyl Sulphate and Protons to Nistone H1

The relationship between the binding of sodium n-dodecyl sulphate and protons to histone H1 has been investigated by equilibrium dialysis and titrimetry. The data cover the pH range 3.2-10 and surfactant concentrations up to 3.0×10-3 mol dm-3. A theoretical approach based on the binding potential concept of Wyman is presented and has been used to make estima...

Effect of NaCl on the self-aggregation of n-octyl beta-D-thioglucopyranoside in aqueous medium.

This report investigates the effect of sodium chloride (NaCl) on the micellization, surface activity, and the evolution in the shape and size of n-octyl beta-D-thioglucopyranoside (OTG) aggregates. By using surface tension measurements, information was obtained on both changes in the critical micelle concentration and adsorption behavior in the air-liquid interface with the electrolyte concentr...

EVALUATION OF THE USE OF ANIONIC/ NONIONIC MIXED MICELLES IN REVERSED PHASE LIQUID CHROMATOGRAPHY OF CHLOROPHENOLS

The use of aqueous mixed micellar system consisting of sodium dodecyl sulfate (SDS) and polyoxyethylene (23) dodecanol (Brij-35) as the mobile phase in reversed-phase liquid chromatography was studied. A group of chlorophenols was used as the test mixture. Adding organic modifier to the system showed that the use of low concentrations of organic additives improves efficiency in SDS/Brij-35 mixe...

The thermal denaturation of adenosine deaminase (ADA) has been investigated in the presence of sodium n-dodecyl sulphate (SDS) over the temperature range of (293-363K) in 2.5 mM phosphate buffer, pH 6.4 by temperature scanning spectroscopy. The interaction of SDS caused the folding of adenosine deaminanse resulting in a decrease of TH (temperature of minimum solubility), TS<...
