RESUMEN
Se presentan los resultados del estudio de los complejos de vanadio(III) con glutatión (GSH, H3L) a 25 °C y en KCl3,0 M mediante medidas de fuerzas electromotrices, emf(H). El análisis de los datos mediante el programa de mínimos cuadrados generalizados LETAGROP indica la formación de cantidades significativas de los complejos VH4l4+, VH3L3+, V(H3L)23+ yv(L)(3L)2+, cuyas constantes de estabilidad fueron determinadas.
The formation of the vanadium(III) complexes with glutathione (GSH, H3L) was studied in 3.0 M KCl at 25 °C by means of electromotive forces measurements, emf (H). The analysis of the potentiometric data by means of the least-squares program LETAGROP indicates the formation of significant quantities of the complexes VH4l4+, VH3L3+, V(H3L)23+ yv(L)(3L)2+, whose stability constants were determined.
