Da. Malikov et al., INFLUENCE OF THE STRUCTURE AND PROPERTIES OF UNSATURATED HETEROPOLYCOMPOUNDS ON AM(III) OXIDATION AND THE STABILITY OF AM(IV) AND AM(VI), Radiochemistry, 35(4), 1993, pp. 459-464
The conditions for oxidation of Am(III) by a mixture of Ag+ and sodium
persulfate in H2SO4 SolUtions containing the ''unsaturated' 11th orde
r heteropolycompounds K7PW11O39, K8SiW11O39, K8GeW11O39, and K9BW11O39
are studied. The conditions for preparing Am(IV) and -(VI) are found
and their stability is studied. This class of heteropolycompounds can
be used in the analytical chemistry of Am.
