Description

An extraction chromatography method with a column of microporous polyethylene supporting tri-n-octylamine was used to separate uranium and thorium from zircon sands. The two elements were determined both by physical-chemical techniques (fluorimetry and colorimetry) and by radiometric techniques (alpha spectrometry) after electrodeposition. Their respective contents agreed well. Furthermore, uranium and thorium isotopes resulted in secular equilibrium in the analyzed material. (author)
