Complexation of calcium and magnesium with adenosine mono, di and tri phosphates has been studied at 25(DEGREES)C and 0.1 M ionic strength. Stability constants for the complexes with unprotonated as well as the monoprotonated forms of these ligands have been determined by potentiometric technique. The enthalpy changes for the complexation reactions have been determined by titration calorimetry. / Complexation of lanthanide ions with adenosine mono and tri phosphates has been studied at 0.1 M ionic strength (NaClO(,4)). The stability constants for unprotonated and monoprotonated complexes have been determined by potentiometry and the heat of complexation have been determined by temperature dependence study of the corresponding stability constants. / Complexation of sodium ions with adenosine triphosphate has been studied to evaluate its effect on the metal complexation study. The corrections are estimated for the observed complexation constants and the thermodynamic parameters. / The studies show that the adenosine phosphates are bound to the alkaline earth cations mainly through the phosphate chain. The interaction of the base (adenine) is either not present or is negligible. The complexation of lanthanide ions by adenosine monophosphate is also mainly through the phosphate chain. However, the complexation of lanthanide ions by adenosine triphosphate is best interpreted in terms of complexation through the phosphate chain as well as the heterocyclic ring. / Source: Dissertation Abstracts International, Volume: 43-01, Section: B, page: 0134. / Thesis (Ph.D.)--The Florida State University, 1982.
