Özet
The thermodynamic parameters of complexes of Cu(II), Ni(II) and Zn(II) cations with hydroxynaphthalin-1-carbaldehydene-1-naphtylamin were determined in 60% (v/v) DMF-water, various ionic strengths (0.07,0.13, 0.2 M NaNO 3) and at different temperatures (25, 30, 35,40 ± 0.1°C) using a spectrophotometric method. The sodium nitrate solution was used to maintain the ionic strengths. The stability constants show an inverse relationship with ionic strengths. The thermodynamic parameters (60% (v/v) DMF-water 60% (v/v) DMF- water (?G0, ?H0, ?S0) based on these formation constants were determined. The acid dissociation constant of ligand was investigated in 60 % (v/v) DMF-water has also been calculated at different temperatures.
