Behaviour of SDS micelles bound to mixtures of divalent and trivalent cations during ultrafiltration

摘要: SDS micelles with bound mixtures of Al 3+ and Zn 2+ cations may flocculate or remain colloidal. When the micellar solution does not undergo flocculation, pattern for rates flux solutions is similar to unbound even lower, remaining mostly constant. However, when part original surfactant has flocculated, permeability membrane colloidal lower than in case micelles, at much concentrations. This be explained by fact that residual material partly flocculated composed larger aggregates. True polyvalent more easily retained within UF systems. The apparent charge inversion observed some /Zn /SDS compositions shown as a true using Perel Shklovskii strongly correlated liquid theory. It phenomenon can compression diffuse layer around micelle build-up rheological barrier resulting capture bulk solution. © 2006 Elsevier B.V. All rights reserved.
