Research Article Study of Cd 2+ - Famotidine Complexes by Polarography

The interaction between Famotidine and Cd2+ was investigated using direct current polarography. The polarographic technique was used to determine the stability constants and thermodynamic parameters such as enthalpy change (ΔH#), free energy change (ΔG#) and entropy change (ΔS#) of Cd2+ complexes with Famotidine. The study was carried out at two different temperatures 20 °C and 30 °C. Cd 2+ -Famotidine complexes were formed in 1:1 and 1:2 ratios. The electrode processes were
