Özet
The hydrolytic behavior of Th4+, UO2 2+, and Ce3+ was investigated using the potentiometric method at elevated temperatures in KC1 medium. For each metal ion, stability constants were obtained from the pH-metric data using the program HYPERQUAD2006. The formation of [Th(OH)]3+, [Th(OH)2]2+, [Th(OH) 3]+, Th(OH)4, [Th4(OH) 8]8+, and [Th6(OH)15]9+ for the thorium ion, [UO2(OH)]+, [(UO2) 2(OH)2]2+, [(UO2),3- (OH)4]2+, and [(UO2)3(OH) 5]+ for the uranyl ion, and [Ce2(OH)] 5+, [Ce2(OH)2]4+, Ce(OH) 3, and [Ce2(OH)5]+ for the cerium ion was taken into consideration. In addition, the effect of temperature on the stability constants was studied, and thermodynamic parameters were derived and discussed. © 2009 American Chemical Society.
