摘要：
The complex species formed between vanadium(III)-picolinic acid with the small blood serum bioligands lactic, oxalic, citric and phosphoric acids, were studied in aqueous solution by means of electromotive force measurements Emf(H) at 25 °C and 3.0 mol⋅dm−3 KCl as the ionic medium. The ternary complexes were studied by potentiometric measurements and the data were analyzed using the least-squares computational program LETAGROP to obtain the respective stability constants and the stoichiometric coefficients of the complexes formed.
