Application of hollow-fiber supported liquid membranes technique to the selective recovery of a low content of copper from a Chilean mine water

Valenzuela,; Basualto,; Tapia,; Sapag, (Elsevier Sci B.V., 1999)

This communication describes the application of a hollow-fiber-type solid supported liquid membrane technique to the selective recovery and enrichment of copper from a Chilean mine water. The membrane extractor works by ...

Transport of molybdenum with Alamine 336 using supported liquid membrane

Marchese, J.; Valenzuela Lozano, Fernando; Basualto Flores, Carlos; Acosta, Adolfo (ELSEVIER SCIENCE BV, 2004-03)

The appropriate experimental conditions of Mo(VI) ion transport across a supported liquid membrane containing Alamine 336 as the mobile carrier dissolved in kerosene solvent have been investigated. The molybdenum flux has ...

Multiresidue determination of pesticides in industrial and fresh orange juice by hollow fiber microporous membrane liquid-liquid extraction and detection by liquid chromatography-electrospray-tandem mass spectrometry

Bedendo, GC; Jardim, ICSF; Carasek, E (Elsevier Science BvAmsterdamHolanda, 2012)

Characterization of chemical kinetics in membrane-based liquid-liquid extraction of molybdenum(VI) from aqueous solutions

Valdés, H.; Romero, J.; Sanchez, J.; Bocquet, S.; Rios, G. M.; Valenzuela, F. J. (2009)

This study aims to describe the mass transfer in a membrane-based solvent extraction system for the extraction of molybdenum(VI) from aqueous solutions, identifying chemical kinetics of the complex formation at the interface. ...

An experimental method to estimate the mass transfer through the interfacial region of liquid membrane systems

Cárdenas, Antonio; Fillous, Lauriane; Rouviere, Jacques; Salager, Jean Louis (Facultad Experimental de Ciencias de la Universidad del Zulia, 2011)

ANTUNES, AM; VOLPE, PLO (Soc Brasileira QuimicaSao PauloBrasil, 1995)

Extraction of Mo (VI) with tertiary amines in a solid-supported liquid membrane reactor

Valenzuela Lozano, Fernando; Pizarro Aguirre, Fernando; Basualto Flores, Carlos; Sapag Hagar, Jaime; Tapia Villanueva, Cristián (SOCIEDAD CHILENA DE QUIMICA, 2001-06)

This communication describes the application of a hollow-fiber-type solid supported liquid membrane technique to the study of recovery and enrichment of molybdenum with Alamine 336 (a long chain tertiary amine) from acid ...

Extraction of molybdenum by a supported liquid membrane method

Basualto Flores, Carlos; Marchese, J.; Valenzuela Lozano, Fernando; Acosta, Adolfo (ELSEVIER SCIENCE BV, 2003-04-10)

This is a report on the extraction of molybdenum(VI) ions using a supported liquid membrane, prepared by dissolving in kerosene, the extractant Alamine 336 (a long-chain tertiary amine) employed as mobile carrier. A flat ...
