  A routine method for the determination of the UU ratio in natural water. Chemical Geology , 25 (4), DOI: /(79) J.F. Alder, B.C. Das. The determination of uranium in geological samples Cited by: @article{osti_, title = {ANALYTICAL METHOD FOR THE DETERMINATION OF FLUORIDE IN URANIUM ORE CONCENTRATES}, author = {}, abstractNote = {The sample is dissolved in sulfuric acid and the fluoride distilled and collected in sodium hydroxide solution. A suitable aliquot of the distillate is adjusted by pH and titrated with thorium. A procedure for the determination of uranium in concentrates is described in this paper, in which reduction is carried out under nitrogen with bismuth amalgam, and the reduced solution is titrated spectrophotometrically with ferric sulphate in a nitrogen by: Uranium is a material of vast technological importance because of its use as a main fuel in nuclear reactors. Determination of uranium concentration in uranium ores has very high importance. Uranium concentration in four different ore samples of Iran uranium ores was determined by XRF and ICP-OES spectrometry methods.

DETERMINATION OF URANIUM CONTENT IN WATER SAMPLES INTRODUCTION This method is designed to measure mass concentration of uranium in samples of natural, drinking and waste water by luminescence using the FLUORAT®M analyzer. MEASUREMENT METHOD Uranium concentration in an aqueous solution is determined by measuring the intensity of retarded. method was developed for the determination of microgram amounts of uranium in water samples. This method allows the determination of uranium concentrations within the inter­ val of to Mg U/l, jthe overall ranging from % to %. Results obtained for water samples from several sources in the State of São Paulo, Brasil, are reported. concentration determination on a reference curve (determined with standard solutions of uranyl nitrate). For Thorium and Iron determination, the method follows the stages for the uranium determination; the only difference consists in the reference solutions. By a priori column separation the superposition of the signals is avoided. ments and isotopes considered are uranium, lead, radium, radium, tritium, and carbon A gross radioactivity survey method and a uranium isotope ratio method are given. When two analytical methods are in routine use for an individual isotope, both methods are reported with identification of the.

  The accuracy and precision of the method were also determined by measuring the concentration of standard uranium solutions in the range 10–50 μg g −1, after appropriate dilution if needed. The results showed that the percentage recovery of uranium was quantitative with good precision (–%). A method has been developed for the determination of the U/ U isotope abundance ratio in sequential extracts of freshwater sediment by means of ICP-MS. Instrument parameters were optimised, and sample pre-treatment procedures developed, to improve the quantification of U. Extracts prepared according to the three-stage BCR sequential extraction protocol were passed through a 2 cm.
