Computer methods for the calculation of complex formation constants by differential pulse polarography

The modification to the DeFord and Hume method for differential pulse polarography is applicable to quasi-reversible and irreversible processes and takes into account any change in the reversibility of the system when the concentration of the ligand is altered. Three computer programs for the calculation of the stability constants are outlined: two of them are based in the weighted least-squares and the third is a simulation process.
