Download or read book Development of Chemical Isolation and Concentration Techniques for Tc-99 Analysis by Resin-bead Mass Spectrometry written by and published by . This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A novel, highly sensitive, isotope-dilution analytical technique for the determination of technetium-99 has been developed around single ion-exchange bead mass spectrometry. Mass spectrometry is much more sensitive than direct counting for the low-energy, low-specific activity, Tc-99 isotope. Further, the point source provided by a single ion-exchange bead leads to a greater signal-to-noise ratio in the mass spectrometric measurement than does conventional application of a solution to the source filament. Recent results indicate a sensitivity greater than 0.1 picogram. Isolation of technetium from the samples occurs after addition of Tc-97 as a yield tracer. A combination of ion-exchange chromatography and ion-association solvent extraction provides decontamination from the potential interferences, Mo-97 and Ru-99. Subsequently, the technetium is loaded onto a pair of anion-exchange beads (diameter approx. 0.3 mm). The noncritical isolation and bead-loading scheme typically concentrates the technetium in the sample by a factor of about a million with overall recoveries exceeding 50%. A variety of environmental samples from the Savannah River Plant (SRP) has been analyzed by this method.

Download or read book The Comparison of Sample Preparation Techniques for the Determination of Technetium-99 in Pure Uranium Compounds and Subsequent Analysis by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) written by PR. Makinson and published by . This book was released on 1995 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this presentation, a procedure for the determination of ng/g levels of technetium-99 in uranium dioxide powder, hydrolyzed uranium hexafluoride (Hex), and uranyl nitrate liquor (UNL) is discussed, and three methods for the dissolution of uranium dioxide are compared. Digestion of uranium dioxide using concentrated nitric acid in a stoppered glass tube gives variable results. A concentrated hydrochloric acid dissolution using microwave digestion in sealed TFE-fluorocarbon PFA digestion vessels gives reproducible results, as does the digestion using dilute nitric acid in open beakers. The effects of the isobaric interference of ruthenium-99 and the molecular interference of 98MoH and the use of suitable algorithms to correct for such interferences are discussed. Compensation of signal suppression due to the uranium matrix is made by the use of matrix-matched calibration standard solutions and instrumental drift is monitored and corrected by the addition of rhodium as an internal standard. A detection limit (2 s) of 0.3 ng g-1 U is achieved using a solution containing 2 g of uranium per litre and a 30-s per isotope acquisition time, using "peak jump" mode.

Download or read book Analysis of Environmental Radionuclides written by Pavel P. Povinec and published by Elsevier. This book was released on 2011-07-28 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to present a state of art summary of current knowledge of methods of assessment of radionuclides in the terrestrial and marine environments. It cover the traditional methods of radioactivity measurements such as radiometrics techniques, but also recent developments in the mass spectrometry sector. The book starts with a short preface introducing the subject of the book, summarising content and philosophy of the book, as well as the most important historical achievements. The scientific topics are introduced by description of sampling methods, optimisation of sampling sites and sampling frequency. The recent developments in radiochemical separation methods using chromatography resins for the treatment of actinides, transuranics and other groups of radioelements are also described. No other book is available covering all aspects of environmental radioactivity measurements, although remarkable progress has been made in detection techniques over the last ten years. At present the new methods enable to carry out investigations which were not possible before, either because of lack of sensitivity or because of the fact that they required too large samples.
