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.en10.1021/je901003pinfo:eu-repo/semantics/closedAccessArticle55620772083Q2
