Thermodynamics of complexation of magnesium and calcium ions with dichloromethylenediphosphonate
Thermodynamic parameters for the complexation of CA 2+ and Mg 2+ ions by dichloromethylenediphosphonate (clodronate) ligand were obtained by potentiometric and calorimetric techniques. The measurements were conducted at an ionic strength of 0.10 M [(CH 3) 4NCl]) and at 25°C. The potentiometric data...

2+ and Mg
2+ ions by dichloromethylenediphosphonate (clodronate) ligand were obtained by potentiometric and calorimetric techniques. The measurements were conducted at an ionic strength of 0.10
M [(CH
3)
4NCl]) and at 25°C. The potentiometric data were consistent with a model involving the presence of ML
2−MHL
− and M
2L species (L = tetranegative clodronate anion). The enthalpies of formation of the ML
2− and MHL
− complexes were obtained from calorimetric data. Attempts to determine the enthalpies of formation of the M
2L species were unsuccessful due to the limited solubilities of these species. |
