Sistemas acuosos bifásicos para la extracción de HNO3
Resumen
La extracción de especies por sistemas acuosos bifásicos (ATPS) ha sido de gran relevancia en los últimos años debido a que son de fácil operación y que no provocan daños en el medio ambiente. No obstante, al formarse por dos fases ricas en agua representan una gran complejidad para comprender los mecanismos de extracción. Así, este trabajo se enfoca en la evaluación del comportamiento de extracción de HNO3 en un sistema ATPS formado por 20% p/p Na2SO4 y 35% p/p PEG-1000. Se evaluó la estabilidad de las ATPS a diferentes concentraciones de HNO3 y se determinó el porcentaje de extracción y el coeficiente de distribución de H+ y NO3- de la fase acuosa a la fase polímero a partir de los cuales se propuso un esquema de extracción.
