Production and stability of tetra- and hexavalent americium in solutions of sodium carbonate
Description
This paper investigates the electrochemical oxidation of americium(III) in solutions of sodium carbonate. At pH = 10, as a result of oxidation, americium(IV) is obtained, while at pH 11, americium(IV) is obtained. A spectrophotometric investigation of the stability of tetra- and hexavalent americium at various temperatures showed that Am(VI) is reduced to Am(V) according to a first-order reaction, the activation energy of which is equal to 63.8 + or - 5.4 kJ/ mole, while Am(IV) disproportionates to form Am(III) and Am(V) and is reduced
