Separación electrodialítica de Cu(II) y As(V) en electrolitos ácidos

Abstract

Se investigó el uso de la electrodiálisis para separar cobre y arsénico desde soluciones ácidas a temperatura ambiente. Se estudió el efecto de la densidad de corriente y grado deacidez del electrolito en la separación a través de experimentos en celda batch de 5 compartimientos durante 3 h. Los parámetros cinéticos indican que la velocidad de transporte de Cu(II) fue de 0,75 mol/h/m2 y de As(V) fue de 0,002 mol/h/m2 a una densidad de corriente de 225 A/m2. Se logró obtener una eficiente separación de Cu(II) y As(V), con la generación de una solución concentrada de cobre sin presencia de arsénico, lo cual fue independiente del grado de acidez de la operación y de la densidad de corriente. El efecto de la distribución de las especies iónicas de As(V) con el pH también se discute.
