The stability constants of the chelates of Co(II), Ni(II), Cu(II), Zn(II), Cd(II), UO2(2+) and VO(2+) with o-(N-α-pyrrolidimino)propanoic acid (H2PP) and o-(N-α-pyrrolidimino)benzoic acid (H2PB) have been determined potentiometrically using Calvin's extension of Bjerrum's method in aqueous medium (μ = 0.1, 0.05 and 0.01 M NaClO4) at 25 deg C, 35 deg C and 45 deg C, respectively.The thermodynamic parameters (ΔG0, ΔH0 and ΔS0) have also been evaluated.Metal chelates have been isolated in the solid state also and characterised on the basis of elemental analyses, magnetic, UV and IR spectral, molar conductance and thermal studies.
