thorium ( Ⅳ) and nitric acid as a function of aqueous HNO3 concentration
extractant concentration and temperature is studied with N-(2-ethyl-hexyl) caprolactam. The extracted species and enthalpy of extraction reaction are evaluated . The third phase formation in extraction of U( Ⅵ)is also studied. In addition
back extraction behavior of U(Ⅵ)and Th(Ⅳ)from organic phase is tested . The results obtained are compared with those obtained by using TBP at the same experimental conditions.
