A NEW METHOD BASED ON PAPER CHROMATOGRAPHY FOR THE ESTIMATION OF THORIUM AND URANIUM IN MONAZITE

Journal Article · · Analytica Chimica Acta (Netherlands)
;
A dioxan-antipyrine solvent mixture is used to separate thorium and uranium on sheet chromatograms from the monazite sand solution. Thorium is estimated by an indirect EDTA titration method, using pyrocatechol violet. Uranium is estimated spectrophotometrically by the hydrogen peroxide method. (auth)
