Abstract

Tantalum is determined by direct current plasma spectrometry after separation of plutonium from solution as PuF/sub 3/. After centrifugation of the PuF/sub 3/ precipitate, a low level of plutonium remains in solution in sufficient quantity to cause spectral interferences. It is necessary to determine the plutonium by dc plasma spectrometry and apply a correction to determine low tantalum concentrations with good accuracy and precision. Tantalum can be determined down to 0.4 ppM in solution with a relative standard deviation of 10 percent. Better precision can be achieved at higher concentrations. The procedure is simple and convenient for glovebox work. 5 references, 1 figure, 1 table.

Measurement of impurities in plutonium metal by rapid ion exchange/direct current argon plasma spectrometry

Conference Maxwell, III, S.; Coleman, J.

A rapid ion exchange/direct current argon plasma (DCAP) spectrometry method is now being applied at the Savannah River Site to provide faster, more reliable assay of key metallic impurities in plutonium metal. These measurements are essential for nuclear materials accountability and enhanced process control. Impurity assays must be performed to ensure that plutonium product specifications are met and to determine the 100% -- impurities plutonium assay used in shipper/receiver calculations. Separation of impurities from plutonium metal is required prior to measurement by spectral techniques since the complex emission spectra of plutonium interferes with the impurity emission lines.

Journal Article Bankston, D; Humphris, S; Thompson, G - Anal. Chem.; (United States)

A technique for the determination of major concentrations of SiO/sub 2/, Al/sub 2/O/sub 3/, Fe/sub 2/O/sub 3/, MgO, CaO, Na/sub 2/O, and K/sub 2/O, minor levels of TiO/sub 2/, P/sub 2/O/sub 5/, and MnO, and trace concentrations of Ba, Cr, Cu, Ni, Sr, V, and Zn, in semi-microsamples 200 mg) of powdered whole rock, is described. Chemically diverse standard reference rocks are used both for calibration and assessment of accuracy. A lithium metaborate fusion melt of each standard or sample is dissolved in dilute HNO/sub 3/ containing Cs/sup +/ at a level of 0.2% (w/v). The resulting solution is usedmore »« less

Determination of arsenic, boron, carbon, phosphorus, selenium, and silicon in natural waters by direct current plasma atomic emission spectrometry

Journal Article Urasa, I - Anal. Chem.; (United States)

A direct current plasma was used to characterize the atomic emission spectrometry of arsenic, boron, carbon, phosphorus, selenium, and silicon. The atomic spectrometric measurements of these elements were evaluated with respect to detection limits, sensitivity, linear dynamic range, precision, interference effects, matrix effects, and element selectivity. In most cases, the observed detection limits and sensitivity are one or more orders of magnitude better than those achievable with other techniques. No significant interference or matrix effects exist in the presence of other chemical species, especially those which are commonly encountered in natural water and wastewaters. The direct current plasma is insensitivemore »« less

TRILAURYLAMINE EXTRACTION: SPECTROGRAPHIC DETERMINATION OF TANTALUM IN PLUTONIUM

Technical Report Ko, R

Ion exchange and tributylphosphate extraction separations of tantalum from plutonium were tried. A trilaurylamine extraction-spectrographic method for the determination of tantalum in plutonium was developed. Plutonium was dissolved in HCl and separated by amine extraction from the undissolved tantalum and from any tantalum that might have dissolved. HF was then added to dissolve all the tantalum and the solution was concentrated by evaporation. Niobium internal standard was added and tantalum determined in the aqueous phase by graphite spark spectrographic analysis. Concentrations of tantalum as low as 50 ppm in 50 mg of plutonium were determined with an estimated relative standardmore » deviation of plus or minus 7%. (auth)« less
Ultra-trace determination of Strontium-90 in environmental soil samples from Qatar by collision/reaction cell-inductively coupled plasma mass spectrometry (CRC-ICP-MS/MS)

Conference Al-Meer, S.; Amr, M.; Helal, A.; ...

Because of the very low level of {sup 90}Sr in the environmental soil samples and its determination by beta counting may take several weeks, we developed a procedure for ultra-trace determination of {sup 90}Sr using collision reaction cell-inductively coupled plasma tandem mass spectrometry (CRC-ICP-MS/MS, Agilent 8800). Soil samples were dried at 105 deg. C and then heated in a furnace at 550 deg. C to remove any organics present. 500 g of each soil samples were aliquoted into 2000 ml glass beakers. Each Soils samples were soaked in 2 ppm Sr solution carrier to allow determination of chemical yield. Themore »« less
