“…In this context, different liquid membrane processes have been proved to be an effective alternative for treatment of cadmium containing effluents/wastewaters [16][17][18][19][20][21]. The supported liquid membrane (SLM) has edge over other membrane processes with respect to its high selectivity, low energy utilization [18] and has been a subject of number of recent investigations for separation of cadmium and other metal ions from wastewaters/effluents using a variety of extractants [22][23][24][25][26][27][28].…”

“…This same extractant was used to investigate the transport of cadmium(II) from neutral and acidic chloride media [93] . The investigation was carried out using two membrane technologies: flat-sheet supported liquid membrane and hollow fiber strip dispersion; in the latter, the rate of transport of cadmium(II) was faster in acidic chloride medium than in the neutral one.…”

The generation of liquid effluents containing organic and inorganic residues from industries present a potential hazardousness for environment and human health, being mandatory the elimination of these pollutants from the respective solutions containing them. In order to achieve this goal, several techniques are being used and among them, supported liquid membranes technologies are showing their potential for their application in the removal of metals contained in liquid effluents. Supported liquid membranes are a combination between conventional polymeric membranes and solvent extraction. Several configurations are used: flat-sheet supported liquid membranes, spiral wounds and hollow fiber modules. In order to improve their effectiveness, smart operations have been developed: non-dispersive solvent extraction, non-dispersive solvent extraction with strip phase dispersion and hollow fiber renewal liquid membrane. This paper overviewed some of these supported liquid membranes technologies and their applications to the treatment of metal-bearing liquid effluents. KeywordsSupported liquid membranes; Metals; Extractants; Ionic liquids; liquid effluents; Environment. Tecnologías de membranas líquidas soportadas en la eliminación de metales de efluentes líquidos ResumenLa generación, por parte de las industrias, de efluentes líquidos conteniendo sustancias orgánicas e inorgánicas, es un peligro potencial tanto para los humanos como para el medio ambiente, siendo necesaria la eliminación de estos elementos tóxicos de las disoluciones que los contienen. Para conseguir este fin, se están aplicando diversas técni-cas y entre ellas las tecnologías de membranas líquidas soportadas, están demostrando sus aptitudes para la eliminación de metales contenidos en efluentes líquidos. Las membranas líquidas soportadas, resultan de la unión de las membranas poliméricas y de la tecnología de extracción líquido-líquido. Este tipo de membranas se pueden utilizar en diversas configuraciones: plana, módulo en fibra hueca y módulo en espiral y para aumentar su efectividad se están desarrollando las llamadas operaciones avanzadas: extracción no dispersiva, extracción no dispersiva con dispersión de la fase de reextracción y empleo del módulo de fibra hueca, con renovación de la membrana líquida. En este trabajo se revisan estas operaciones de membranas líquidas soportadas y algunas de las aplicaciones de las mismas, en el tratamiento de efluentes líquidos conteniendo metales. Palabras claveMembranas líquidas soportadas; Metales; Agentes de extracción; Líquidos iónicos; Efluentes líquidos; Medio ambiente.

This paper presents study on the facilitated transport of cadmium(II), cobalt(II) and nickel(II) ions from aqueous chloride solutions through polymer inclusion membranes (PIMs) with phosphonium ionic liquid. Cyphos IL 101 (trihexyl(tetradecyl) phosphonium chloride) was used as a selective carrier for synthesis of cellulose triacetate membranes containing o-nitrophenyl pentyl ether (ONPPE) as a plasticizer. Effect of different parameters such as hydrochloric acid concentration in the source phase as well as ion carrier concentration in the polymer membrane on metal ions transport has been investigated. Cd(II) was transported preferably from hydrochloric acid solutions containing Co(II) and Ni(II) through PIM containing 18.8 wt.% CTA and 26.0 wt.% Cyphos 101 and 55.1 wt.% ONPPE into 0.5 M HNO 3 as the receiving phase. The obtained results suggest that there is a possibility of application of this membrane with Cyphos IL 101 as ion carrier for separation of Cd(II) over Co (II) and Ni(II) from hydrochloric acid solutions.Keywords: cadmium(II), cobalt(II), nickel(II), Cyphos IL 101, polymer inclusion membrane Przeprowadzono badania transportu jonów Cd(II), Ni(II) i Co(II) z wodnych roztwo rów kwasu solnego przez polimerowe membrany inkluzyjne (PIMs) zawierające fosfoniową ciecz jonową -Cyphos IL 101 (chlorek triheksylo(tetradecylo) fosfoniowy) w roli selektywnego przenośnika jonowego. Rolę polimerowej matrycy w membranie pełnił trioctan celulozy (CTA). Jako plastyfikatora użyto eteru nitrofenylopentylowego (ONPPE). W wyniku badań określono wpływ różnych czynników, takich jak stężenie kwasu solnego w fazie zasilającej, jak również stężenie przenośnika w polimerowej membranie na selektywność i efektywność transportu badanych jonów metali. Jony kadmu(II) były selektywnie transportowane z roztworów kwasu solnego zawierającego jony niklu(II) i kobaltu(II) do 0,5 M roztworu kwasu azotowego(V). Uzyskane wyniki wskazują, że istnieje możliwość zastosowania procesów transportu przez polimerowe membrany inkluzyjne z cieczą jonową w roli selektywnego przenośnika do rozdzielania jonów Cd(II) od Ni(II) i Co(II) z roztworów kwasu solnego.
