The proton-ligand stability constants of DTDAA and DGA and the stepwise stability constants of their chelates with VO(IV) have been determined in aqueous medium by potentiometric method at different ionic strengths, (0.1, 0.2 and 0.3M NaCIO4) and temperatures (25° and 35°). Thermodynamic stability constants and thermodynamic parameters (∆G°, ∆H° and ∆S° ) have been calculated.
