Determinación espectrofotométrica de Nd(III) en sistemas acuosos bifásicos
Resumen
En este trabajo se evaluó la determinación espectrofotométrica de Nd(III) usando el 4-(2-piridilazo)resorcinol (PAR) como ligante y su aplicación a un sistema acuoso bifásico (polímero-sal). Se analizó el efecto que tiene la relación metal:ligando, presencia de sal (Na2SO4) y polímero (polietilenglicol) en la determinación de Nd(III). Una vez definidas las condiciones de medición, se evalúo extracción de Nd(III) en un sistema de sistema acuoso bifásico compuesto por 20% p/p Na2SO4/H2O y PEG-1000/H2O al 35% p/p en diferentes condiciones de acidez: sin ácido, 0.1 mol L-1 HCl y 0.1 mol L-1 H2SO4.
