Abstract

EXTRACCION DE CATIONES A PARTIR DE SUS DISOLUCIONES ACIDAS. CONSISTE EN LA CREACION DE UNA MICROEMULSION ENTRE UNA CAPA DE DISOLUCION ACUOSA Y UNA CAPA DISTINTA DE LIQUIDO HIDROFOBO. LA MICROEMULSION SE PREPARA POR EDICION DE UNO O VARIOS AGENTES TENSIOACTIVOS Y DE UNO O VARIOS COTENSIOACTIVOS, EN CONCENTRACIONES DE AGENTES TENSIOACTIVOS DE 0,025 A 0,4 MOL/L DE LIQUIDO HIDROFOBO Y 0,1 A 3 DE ALCOHOLES, POR LITRO DE LIQUIDO HIDROFOBO QUE DESPUES DE AGITACION EL SISTEMA SE PRESENTA EN FORMA DE TRES CAPAS DIFERENTES, LA INTERMEDIA CONSTITUIDA POR UNA MICROEMULSION. LA CAPA INTERMEDIA ES REUTILIZABLE PARA UNA NUEVA EXTRACCION, MIENTRAS QUE LA CAPA HIDROFOBA SE SOMETE A RECUPERACION DE LA SUSTANCIA Y LA CAPA ACUOSA SE EVACUA. TIENE APLICACION EN LA HIDROMETALURGIA PARA LA EXTRACCION DE LOS METALES DE LOS GRUPOS II EN VIII DE CLASIFICACION PERIODICA DE ELEMENTOS.
