Description
The precipitations of thorium and uranium(VI) sulfito complex ions with hexammine cobalt(X) chloride as the precipitant have been studied.<BR>The orange-colored uranium(VI) precipitate obtained is [Co(NH3)6]4[UO2(SO3)3]322H2O, which is in the form of square bipyramid, about 4 μm across in a cubic symmetry of the diamond type with a =10.40 Å It decomposes to an oxide mixture of Co304 and U3O8 above 850°C in the air through a sulfate mixture of CoSO4 and UO2SO4.<BR>Composition of the thorium precipitate varies with the precipitation conditions. Therefore, it is considered that the thorium precipitate contains thorium hydroxide and basic thorium sulfite.
