Description

An extraction chromatographic method based on microporous polyethylene supporting TOPO was used to separate uranium and 226Ra from phosphorites and their industrial derivatives. Uranium was then determined by fluorimetry and by alpha spectrometry after electroplating, and radium by precipitation and alpha counting. The method was checked by using IAEA phosphorite sample. Some phosphorite, phosphoric acid and plaster samples supplied by an Italian industrial plant were analyzed. Uranium isotopes always resulted in radioactive secular equilibrium.
