Micellization of sodium dodecyl sulfate and polyoxyethylene dodecyl ethers in solution
The effect of polyoxyethylene type nonionic surfactants (C12En n=3, 4, 5, 6, 7 and 8) on the aqueous solution of sodium dodecyl sulfate (SDS) in absence and presence of NaCl was examined using small-angle neutron scattering (SANS), dynamic light scattering (DLS), and viscosity measurements. Upon addition of C12En, micellar size of SDS was found to increase significantly, and such micellar elong...
متن کاملIsolation and Characterization of SDS (Sodium Dodecyl Sulfate) Degrading Organisms from SDS Contaminated Areas
Surfactants are synthetic organic chemicals that are formulated to have cleansing or solubilisation properties with the development of the industrial economy and increase in population density, surfactants have become one of the most widely disseminated xenobiotics to enter the aquatic environment, creating a serious environmental problem. Principal criterion for the ecological behavior of surf...
متن کاملConductometric Study of the Thermodynamics of Micellization of Sodium dodecylsulfate (SDS) in the Presence of Some Aromatic Ammonium Salts
The effect of three organic aromatic salts - Phenyltrimethylammonium (PhTMAB), benzyltrimethylammonium (BzTMAB) and benzyltrimethylammonium (BzTEAB) bromides - on the micellization of sodium dodecylsulfate has been investigated by conductometric method. The critical micelle concentration (CMC) values were found to decrease with increase in the concentration of the aromatic ammonium salts. Therm...
متن کاملSimulations of micellization of sodium hexyl sulfate.
Micellization of the ionic surfactant sodium hexyl sulfate has been studied using atomistic explicit-solvent molecular dynamics simulations with and without excess NaCl or CaCl(2). Simulations were performed at surfactant loadings near the critical micellization concentration. Equilibrium micelle size distributions and estimates of the critical micellization concentration obtained from the simu...
متن کاملThermodynamics of micellisation: Sodium dodecyl sulfate/sodium deoxycholate with polyethylene glycol and model drugs
Variations in the critical micelle concentration (CMC) have been determined for sodium dodecyl sulfate and sodium deoxycholate (NaDC) in the presence of five drugs and polyethylene glycol (PEG) at 298.2, 304.2 and 310.2 K. From these data, thermodynamic parameters associated with the micellisation process (∆Gmic, ∆Hmic and ∆Smic) were calculated. In the presence of some drug-based compounds the...
