“…The values obtained were compared with those reported by Perkins et al [20] for BGS IGS 35 by solution ICP-MS method and those reported by Singh et al [7] for CERAM 2CAS15 after KHF 2 -NaF fusion analyis by ICP-MS without separation. Almost all the elements of interest were recovered quantitatively and the variations were within the experimental error allowed.…”

In this paper an accurate and highly reproducible separation method for determination of trace amounts of uranium and rare earth elements (La-Lu and Y; abreviated as REEs) in the refractory zircon mineral concentrates by inductively coupled plasma-optical emission spectrometer (ICP-OES) is described. The precipitation method used for separation of zirconium is simple, selective, rapid and environmental friendly. All the 16 geochemically important analytes were determined in a single solution with marginal improvement in detection limits (1.2-4.5 times) after separation. The method was validated by analyzing certified reference materials.

Direct determination of uranium and thorium in minerals by time-of-flight mass spectrometry with pulsed glow discharge

et al. 2015

A direct method of uranium and thorium determination in non-conducting geological samples using timeof-flight mass spectrometry with pulsed glow discharge was proposed. The following rock specimens were analysed: metamict zircon, metamict rinkite, metamict samarskite (Y-Fe-niobate), pyrochlore and jacinth.For sample sputtering a combined hollow cathode cell of high purity aluminium or tantalum hollow cathodes was used. Powdered or monolith samples were pressed into the surface of the powdered metal prior to analysis. Model samples (artificial mixtures of oxides) were proposed for calibration; additionally, relative sensitivity factors, internal standardisation and standard additions were employed.For validation, IAEA artificially prepared uranium ore reference material was analysed. For additional validation, the obtained results for real mineral samples were compared to the results of inductively coupled plasma optical emission spectrometry after sample dissolution and semi-quantitative data of energy dispersive X-ray spectrometry. Limits of detection (3s) for the designed method were 0.3 ppm for uranium and 0.5 ppm for thorium, which is comparable to laser ablation inductively coupled plasma mass spectrometry. The method was also tested for capability to measure isotope ratios for lead and uranium without specific isotope calibration. Acquired isotopic ratios of uranium and lead corresponded to their natural abundances within the experimental error.

“…It was recommended that a test portion of #100 mg of ultrane powder (<30 mm nominal particle size) be taken to prevent the formation of Alkali fusions are preferred by many laboratories because they are relatively rapid and digest totally the resistant accessory minerals, but they result in a solution with high TDS content. Singh et al 287 compared two fusion procedures for the dissolution of zircon prior to the measurement of the REEs, Th and U: one based on sodium peroxide and the other using a 3 + 1 mixture of KHF 2 and NaF. Unfortunately, certied values were unavailable for both of the two zircons analysed, although data from both methods were comparable with each other and any available published data.…”
