Özet

The complexation of guanine with Th4+, UO2 2+, and Ce3+ was investigated using the potentiometric method at a constant ionic strength of I = 0.10 mol•dm-3 (KCl) in aqueous solutions at elevated temperatures. For each metal ion, stability constants were obtained from the pH-metric data using the program HYPERQUAD2006. The formation of monomeric and polymeric species was taken into consideration for each ion at (25, 37, and 45) °C. The thermodynamic parameters for the formation of the guanine complexes were calculated. In conclusion, it is indicated that the values of the stability constants change at various temperatures. © 2010 American Chemical Society.
