Determination and calculation of micro-structural parameters of SDS/BA/H2O micelle

A model-based analysis of electrodialysis fouling during pulsed electric field operation

“…SDS is known to foul IEMs by forming a fouling layer on the anion-exchange membrane [49] but is also known to adsorb into the larger pores of the anion-exchange membrane [50]. The size of a hydrated molecule of SDS is estimated to be 0.41 nm radially and 2 nm axially [51]. Compared to the reported effective pore size from lower than 1 to up to 15 nm for homogeneous membranes like the Fujifilm type-II anion-exchange membrane used in this study [52], it is a reasonable hypothesis that a fraction of SDS can migrate into the larger pores of the membrane but it seems unlikely that SDS can fully migrate from the diluate compartment to the concentrate compartment and contribute to the membrane flux.…”

Determination of Physicochemical Parameters of Sodium Dodecyl Sulfate in Aqueous Micellar Solutions Containing Short-Chain Alcohols

“…The micellar and thermodynamic properties of surfactants are mainly dependent on pH, pressure, temperature, ,− and added electrolytes, ,,− cosurfactants, and cosolvent. − Because surfactant micellar solutions generally are used as carriers of active, lipophilic ingredients (antioxidants, vitamins, drugs, antimicrobials, phytochemicals) having poor water solubility which directly restricts their applicability, a cosolvent added improves their transfer by increasing the viscosity and volatility of solutions . Owing to wide applications of micellar systems and water–organic solvents, surfactant aggregations in aqueous–organic solvents and nonaqueous polar medium have been extensively studied, − and sodium dodecyl sulfate (SDS), as a very popular ionic surfactant, has been the most often used surfactant in various investigations. ,,,,,,,,− …”
