Microtitrimetric determination of uranium in tributylphosphate (30%)-n-dodecane-nitric acid medium in the presence of excess of iron, magnesium and aluminium.
A method is described for microdetermination of uranium in aqueous phases containing nitric acid, iron, magnesium, aluminium and traces of TBP, and in organic phases containing TBP, n-dodecane and nitric acid. Treatment of the organic phase strips the uranium, reduces it to U(IV), and destroys any nitrite present.
