THE DIRECT DETERMINATION OF URANIUM IN CONCENTRATES BY SPECTROPHOTOMETRIC TITRATION WITH FERRIC SULPHATE
Journal Article
·
· Analytica Chimica Acta (Netherlands)
A direct method is presented for the determination of uranium in concentrates by spectrophotometric titration with ferric sulphate after a bismuth amalgam reduction, the oxidation of U(IV) by Fe(III) was found to be rapid and complete at room temperature. Copper, molybdenum, and vanadium interfere to some extent, and their maximu permissible concentrations are discussed. A complete determination may be carried out in slightly more than an hour with a precision of 2 to 3 parts per thousand. An Uvispek spectrophotometer was adapted for spectrophotometric titrations without modification of the instrument. (auth)
