Abstract

A kinetic method of spectrofluorimetric determination of V(V) is established based on the reaction of the cation with 1-amino-4-hydroxyanthraauinone, in which formation of an oxidation product of the reagent takes place. The variables that influence the development of the fluorescence are studied and the influence that the presence of foreign ions may cause is determined, finding that only Ce(lV) interferes seriously when it is in concentrations higher than that of V(V). The method is applied to the determination of non volatile vanadium in petroleum crudes.
