ABSTRACT
The complexes formed between 8-[o-hydroxyphenylazo]-7- hydroxy-4-methylocumarin [1] and Ce[3], Th[4] and U[6] were studied spectrophotometrically in solutions. The different complexes were characterized and their stoichiometric ratios were investigated. Methods for the spectrophotometric determination of these metals and spectrophotometric titrations using EDTA were reported. The effect of the presence of several metal ions was also reported
