Thermodynamic study of interaction between some transition metal ions and L-Alanine
Using UV-vis spectrophotometic method, the formation constants for interaction of Cd2+(aq) andCo2+(aq) ions with L-Alanine were experimentally studied at pH = 4.1 ± 0.01 (50mM of potassiumhydrogen phthalate buffer), ionic strength of 0.1M potassium nitrate and at 5 differenttemperatures 15,20, 25,30 and 35°C. The optical absorption spectra of mixtures containingconsidered cations and L-Alanine ...

The determination of formation constants of binary inner transition metal complexes where M=Y(III) or La(III) or Ce(III) or Pr(III) or Nd(III) or Sm (III) or Gd (III) or Dy (III) or Th(IV) andL = Creatinine have been carried out using Irving–Rossotti titration technique in aqueous mediaat different temperatures and at ionic strength. To understand more about the nature ofequilibrium involving i...

15 صفحه اولThermodynamic and kinetic properties of metal ions in aqueous solution
While it is evident that a metal ion in aqueous solution interacts electrostatically with water molecules and the anions present in the solution, it is equally apparent that often the metal ion chemically combines with varying numbers of ions or molecules to form complex species. This tendency towards coordination complexing is observed most often with the transition metals and results in a ser...
