Description

Kinetics of electrochemical oxidation of Am(III) and Am(V) ions on Pt electrode in concentrated HNO3 solutions containing potassium phosphotungstate K10P2W17O61 is studied by spectrophotometric method. It is shown that processes take part in accordance with equation of rate law for reversible reaction. Direct reaction is described by equation of the first order with respect to Am(II) and Am(V) ion concentrations. And back reaction is described by equation of the zero order

Abstract (Russian)

Спектрофотометрическим методом изучена кинетика электрохимического окисления ионов Am(III) и Am(V) на Pt электроде в концентрированных растворах HNO3, содержащих фосфорвольфрамат калия K10P2W17O61. Процессы протекают в соответствии с уравнением закона скорости обратимой реакции. Прямая реакция описывается уравнением первого порядка относительно концентрации ионов Am(III) и Am(V), а обратная реакция - уравнением нулевого порядка
