Determinación espectrofotométrica de cobalto como TTHA-Co.

Abstract

Es conocido que el alto potencial del sistema Co(III)/Co(II) disminuye considerablemente en presencia de ligandos poliaminopolicarboxilados debido a la circunstancia de que los quelones de Co(III) poseen constantes de formación mucho más altas que los correspondientes de Co(II) en presencia de aquellos ligandos quelantes. Los estudios y aplicaciones basados en este hecho fueron iniciados con el empleo del ácido etilenodiaminotetraacético (AEDT) por Schwarzenbach en 1949 (1). Desde entonces, los diversos trabajos publicados sobre este tema han tenido como principal objetivo proponer nuevos métodos para la determinación del cobalto en diversos materiales.
