The analysis of the potentiometric data by means of the least-squares computational program LETAGROP, indicates the formation of significant quantities of the complexes [VHL], [VL]- and [V(OH)L]2- together with their respective stability constants of each complex. In addition to the LETAGROP analysis UV-Vis spectrophotometric measurements were done in order to make a qualitative characterization of the complexes formed in aqueous solution %K Vanadium(III) complexes %K Stability constants %K CDTA %K Potentiometric Analysis %K Spectrophotometric measurements %U http://www.saber.ula.ve/bitstream/123456789/34551/1/ac6%206%283%29%2095-99.pdf
