Keywords:uranium iron oxide, Dissolution behaviour, Organic acid

UFeO4 was prepared by the reaction of magnetite with U3O8 and its solid state was characterlized by XRD. The sample was added to solutions in the atmosphere for the static leaching test. Finally, thermodynamic simulation of apparent solubility was performed on the basis of the dissolution behavior.
