Rapid determination of uranium in geochemical samples by paper chromatography

J. Plamondon

Concentrations of uranium as low as 1 ppm are determined in soils and sediments by ascending paper chromatography, subsequent to a hot nitric acid attack of the samples. The reagent 1-(2-pyridylazo)-2-napthol (PAN), which is used to develop the chromatograms, is capable of detecting 0.05 micrograms of uranium. The method is rapid and inexpensive.
