摘要：
Proton dissociation constant of the ligand and the stability constants of the complexes of Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) with 2-hydroxy-benzflidine-o-aniinobenzothiazole have been determined potentiometrically at 30 +/- 0.1degreesC and at ionic strength 0.1 M in 75: 25 (V/V) dioxane-water medium, log K-1 and log K-2 values have been determined. The stabilities of the chelates follow the order Cu > Cd > Co > Ni > Zn.
