Application of laser-induced fluorescence for determination of trace uranium, europium and samarium

Solid-phase extraction–spectrophotometric determination of uranium(VI) in natural waters

“…There are various techniques for the determination of total uranium from very high to very low concentrations reported such as voltammetry [6], polarography [7], fluorimetry [8,9], X-ray fluorescence spectroscopy (XRF) [10], α-spectrometry [11,12], spectrophotometry [13,14,15,16], and ICP spectroscopy [17,18].…”

Optimized and validated spectrophotometric method for the determination of uranium(VI) via complexation with meloxicam

“…There are various techniques such as thin layer chromatography [3], gravimetry [4], titrimetry [5], fluorimetry [6,7], potentiometry [8], polarography [9], X-ray fluorescence [10], inductively coupled plasma mass spectrometry [11] and spectrophotometry [12][13][14][15][16][17][18] for the determination of uranium. The method based on gravimetry requires absence of or prior separation of interfering elements.…”

Optimized and validated wavelength-dispersive X-ray fluorescence spectrometry (WDXRF) method for the determination of uranium in phosphogypsum

“…There are various techniques for the determination of the uranium such as the gravimetric [5][6][7], the volumetric [8], the fluorimetry [9][10][11][12], the potentiometry [13], the polarographie [14], the X-ray fluorescence spectrometry (XRF) [15][16][17], and the inductively coupled plasma coupled to mass spectrometry [18][19][20].…”
