Uranium is reported to be present in phosphate fertilizers. The recovery of uranium from the fertilizers is important because it can be used as fuel in nuclear reactors and also because of environmental concerns. For both these activities suitable method of uranium determinations at trace levels in these fertilizers are required. Studies have been initiated for such TXRF determination of uranium and the results are reported in the present paper. For TXRF determinations the fertilizer samples were processed with nitric acid and the uranium present in it was removed by solvent extraction using tri-n-butyl phosphate as the extractant. The organic phase containing uranium was equilibrated with 1.5% suprapure nitric acid to bring out uranium in aqueous phase. This aqueous phase was mixed with internal standard Y and the TXRF spectra were measured by depositing samples on float glass supports. The amounts of uranium in four fertilizer samples of Hungarian origin were determined by processing these TXRF spectra. Uranium concentrations in two fertilizer samples were found to be in the range of 4-6 μg/g, whereas two fertilizer samples did not show the presence of uranium. The precision of the TXRF determination of uranium was found to be better than 8% (1σ ).

Grazing incidence x‐ray fluorescence (GIXRF) analysis technique has the potential of being one of the most powerful and versatile methods for characterization of layered materials, as it combines features of both x‐ray reflectivity (XRR) and x‐ray fluorescence techniques. GIXRF technique allows non‐destructive evaluation of layer thickness, interface roughness, interlayer formation and depth profiling for an impurity element inside a layer medium or in the substrates. A computer program ‘CATGIXRF’, has been developed for GIXRF characterization of thin film and surfaces. Methodology of the program and its various features has been discussed in detail. The program offers analysis of GIXRF and XRR data simultaneously. The utility of the program has been demonstrated by example calculations and by providing a few examples of XRR and GIXRF characterization of a variety of thin‐layered materials.
