摘要: The protonation equilibria of glycyl-glycine and glycyl-valine their complex formation with thorium(IV) ions in aqueous solution were studied over a wide range pH values (2 to 12) using combination potentiometric, cyclic voltametric, spectrophotometric methods at constant temperature (25 °C) ionic strength (0.1 mol ·dm -3 sodium perchlorate). redox properties the species obtained by voltametry technique have confirmed results. Least-squares regression calculations are consistent ThL 3+ , ThHL2 ThL2 2+ for systems, where L represents each peptide. Finally, concentrations plotted different discussed.
