A polarographic study of uranyl-salicylate and uranyl-phthalate complex formation in acidic solutions

The d.c and a.c polarography and cyclic voltametrry ware applied to the study of uranyl-salicylate and uranyl-phthalate complex. The study was limited to the pH range <5, because insoluble uranyl-hidroxydes are formed above this pH value. Uranyl-salicylate and -phthalate are irreversibly reduced. The electrode proces is preceded by the chemical reaction of the complex whit protons. By thic reaction the alectroactive species whit the charge z=+2 is formed, which was connected whit the carge of the "free" uranyl-ion.
