Use of Micellar-Enhanced Ultrafiltration at Low Surfactant Concentrations and with Anionic–Nonionic Surfactant Mixtures

Apparent Binding Degree of a Counterion and Micellar Composition in Cationic and Nonionic Surfactant Mixed Solutions at CMC

“…A number of solution properties for mixed surfactant systems have already been published (1). In the last five years, several papers on mixtures of nonionic and ionic surfactants using capillary electrophoresis (2), molecular thermodynamic theory (3), potentiometry (4), regular solution theory (5,6), small-angle neutron scattering (7)(8)(9), surface tension (10,11), ultrafiltration (12,13), volumetry (14), and so on have been also published. 1 Fax: +81-93-693-3201.…”

Comparison of Polysulfone and Ceramic Membranes for the Separation of Phenol in Micellar-Enhanced Ultrafiltration

“…Micellar-enhanced ultrafiltration (MEUF) has been proposed as a feasible method to separate organic pollutants (1)(2)(3)(4)(5)(6)(7) or metal ions (8)(9)(10)(11)(12)) from aqueous streams. Surfactants dissolved in water tend to self-aggregate, forming micelles, which have a hydrophobic core and a hydrophilic surface.…”

Ultrafiltration and Alumina Adsorption of Micelles for the Preconcentration of Copper(II) in Water

“…This process has been studied for the removal of organic pollutants and heavy metal ions from water. [3][4][5][6][7] To the best of our knowledge, however, MEUF has not been used for the preconcentration of trace metals at ng ml -1 levels before the instrumental determination steps.…”
