IMPROVEMENTS IN OR RELATING TO A METHOD OF TESTING FOR URANIUM AND APPARATUS THEREFOR

Patent ·
OSTI ID:4005651
A method of testing and production control for uranium and its compounds and the apparatus therefor is described. The method and apparatus for testing an organic solvent for the presence of uranium consists of a liquid-liquid extraction column for washing the solvent with an aqueous solution of a colorimetric agent, ammonium thioglycollate, so as to bring the uranium into the aqueous solution. There consists controls for feeding the solvent and aqueous solution to the column, an absorptiometer having two cells in series, passages cornecting the first cell with the aqueous outlet from the liquid-liquid extraction column, and passages for feeding a decolorizing agent, carbon dioxide, to the colored solution after it leaves the first cell and before it enters the second. The organic solvent is washed with EDTA sodium salt to remove thorium before washing with ammonium thioglycollate. (N.W.R.)
