Micellar studies of magnesium soaps using ion-selective electrode / Lal Chand Heda in TENSIDE, SURFACTANTS, DETERGENTS, Vol. 45, N° 5/2008 (09-10/2008)
[article]
Titre : Micellar studies of magnesium soaps using ion-selective electrode Type de document : texte imprimé Auteurs : Lal Chand Heda, Auteur ; S. Mosalpuri, Auteur ; C. Pareek, Auteur ; D. Pareek, Auteur Année de publication : 2008 Article en page(s) : p. 268-273 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Ion-selective electrode Micellization EMF (Electromotive Force) Hydrophilic oleomicelle Lipophilic hydromicelle Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Magnesium soaps of caproic and caprylic acids were prepared and a cell was set up for the measurement of EMF (electromotive force) of the cell containing referred soap solutions in methanol water solvent system with the aid of ion-selective electrode. The critical micelle concentration of soap solutions was determined by plotting the electromotive force of the cell against soap concentration. The critical micelle concentration of these soap solutions varies with increase in chain length of the fatty acids in the soap. The energetic studies of the system have been carried out from the electromotive force values of the cell containing soap solution to ascertain the chain length compatibility and agglomeration profile. The values of free energy change are negative indicating the spontaneity of cell reaction and decreases with increasing soap concentration while increases with the increase methanol concentration in solvent mixture.

VitaminesTags : Thin layer chromatography (TLC) Vitamins Surfactants Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : The separation efficiency of micellar solutions in thin layer chromatography of hydrophilic vitamins (B1, B9, B12 and C) has been examined using silica gel as stationary phase. The best results were obtained with mixed micelles (aqueous solution of anionic SDS (0.5%) plus non-ionic Triton X-100 (0.5%) surfactants) and butanol (9:1 v/v) as mobile phase. The proposed method is applicable to the identification and separation of vitamins (B1, B9 and C) present in drug samples (Becosule and Celin). The separation 1 µg of vitamin C from milligram quantities (up to 0.50 mg) of vitamin B1 has been successfully realized. Effect of metal ions as impurities on the separation of B1, B9 and vitamin C and limit of detection of these vitamins have been examined.

Critical micelle concentrations (CMC) were estimated from the dependence of the specific conductivity on molarity of the surfactants. It was determined that the temperature dependence of CMC is U-shaped with a minimum shifting toward higher temperatures with decreasing chain length of the alkyl group. Quantities characterizing behaviors of surfactants below and above CMC were calculated and compared from conductivity measurements. Measured and calculated values of studied compounds were also compared with results of many other authors. The paper has the form of a minireview. It is a comparison of the presented experimental data of alkyltrimethylammonium bromides (C6– C18) with earlier works reported. Note de contenu : - EXPERIMENTAL : Materials - Methods
