Abstract
The d. c. and a. c. polarography and cyclic voltammetry were applied to the study of uranyl-salicylate and uranyl-phthalate complexes. The study was limited to the pH range <5, because insoluble uranyl-hydroxydes are formed above this pH value. Uranyl-salicylate and -phthalate are irreversibly reduced. The electrode process is preceded by the chemical reaction of the complex with protons. By this reaction the electroactive species with the charge z = +2 is formed, which was connected with
the charge of the »free« uranyl-ion.
