Description

The determination of uranium in natural waters by X-ray fluorescence (XRF) analysis after its preconcentration with some organic precipitants is described. 109Cd source is used for the excitation of L-series X-rays of uranium. Separation yield, kinetics of coprecipitation and the possibility of preparing thin-layer samples for XRF analysis were studied in detail for uranium concentration with α-nitroso-β-naphthol, methylene blue with ammonium thiocyanate, tannin with urotropine and other precipitants. A procedure using coprecipitation of uranium with α-nitroso-β-naphthol from 500 ml samples of surface or waste waters is proposed. (author)
