MEASUREMENT METHOD OF URANIUM ISOTOPE IN AQUEOUS SOLUTION

摘要

the present invention is a liquid scintillation enumeration (liquid scintillation counting method) by isotope ratio for the information provided and, extraction efficiency, and excellent detection limits and measurement efficiency, as an aqueous solution in the measurement is about uranium isotope uranium isotope measurement method easy solution, the first step, the aqueous solution to prepare an aqueous solution containing uranium isotopes pH after the second separation stage to adjust the (hydrogen ion concentration), the third step of the pH by mixing a solution containing the organic material to the aqueous solution adjusted to produce a mixture, the aqueous layer and oil layer in the mixture, the a fourth step of removing the water layer, washing the separated oil layer the fifth step and the sixth step of measuring a cleaned uranium isotopes contained in the oil layer; include, and wherein the sixth step is a liquid scintillation factor method (liquid scintillation counting method) and to measure the uranium isotope characterized by. ;
