Application of the deford and hume method modified for quasi-reversible and irreversible processes to the chelates of Bi(III) with azomethine derivatives of 2-benzoylpyridine

The polarographic behaviour of the bismuth complexes of the oxime, hydrazone and thiosemicarbazone of 2-benzoylpyridine has been studied by differential pulse polarography. The DeFord and Hume method, modified for use with quasi-reversible and irreversible processes, has been applied for the calcula...

Description
Summary:The polarographic behaviour of the bismuth complexes of the oxime, hydrazone and thiosemicarbazone of 2-benzoylpyridine has been studied by differential pulse polarography. The DeFord and Hume method, modified for use with quasi-reversible and irreversible processes, has been applied for the calculation of the formation constants of these chelates, which exhibit different degrees of reversibility in their electroreduction.
