详细

Gas-phase conversion of metallic U, Zr, and Al into water-soluble compounds in the NOx–H2O (vapor)–air and HNO3 (vapor)–air atmospheres was studied. Monolithic Umet and powdered Zrmet undergo gasphase conversion to form water-soluble compounds (nitrates, hydroxynitrates), whereas monolithic Zrmet remains unchanged. The degree of conversion of Almet into water-soluble compounds in the examined nitrating media at 25–150°С does not exceed 10%. The principal possibility of separating U from Al and Zr by gasphase conversion of monolithic samples in a nitrating atmosphere was demonstrated.
