Solvent extraction of uranium(VI) from industrial and analytical grade phosphoric acid using organic extractants in kerosene with variable content of aromatic hydrocarbons

Abstract The distribution ratio of U(VI) between phosphoric acid, industrial and analytical grade, and kerosene solutions of D2EHPA-TOPO extractants with variable amount of aromatic hydrocarbons has been studied. Under these conditions it was observed that the content of aromatic hydrocarbons in the diluent as well as other ions present in industrial phosphoric acid play a significant role in the extraction of uranium(VI).
