Description
The effect of the mechanical treatment of U3O8 in a planetary ball mill in air or as a suspension in benzene solution of thyolilthreefluoroacetone (TTA) on the nature of the oxide and on the leaching of U and 234Th into diluted aqueous solutions of HCl, Na2EDTA and NaCl has been studied. Transformation of U3O8 to UO2, is much stronger expressed when the mechanoactivation is performed in air is established. The leaching behavior of U and Th depends significantly on the activation mode and on the leaching reagent nature. The role of mechanochemically enhanced UO2-ThO2 solid solution formation for the observed effects is discussed. (author)
