Monomer—micellar equilibrium of aqueous surfactant solutions by the use of ultrafiltration

摘要: Abstract Ultrafiltration is used to separate the monomer from a solution containing both and micelles. Critical values of filtration rate, salt concentration, surfactant hydrocarbon tail length which permit sharp separation have been identified. These vary depending on type membrane used. A system two different molecules has studied composition mixed micelles measured directly for first time. Mixtures alkyl benzene sulfonates found exhibit ideal behavior.
