Abstract

Procedimiento para la extracción selectiva de metales de sus soluciones acuosas, que contienen los citados iones, caracterizado porque comprende ajustar las citadas soluciones acuosas hasta que se obtenga un cierto valor de pH y tratar las soluciones así preparadas con una solución de ácido neo-alquil-hidroxámico en un disolvente orgánico, con lo cual el ión metálico pasa a la solución orgánica del ácido neo-alquil-hidroxámico con factores de separación con relación a los restantes iones que dependen del pH al cual se ha ajustado la solución acuosa a extraer y de la concentración del ácido hidroxámico en el disolvente orgánico.
