Uranium analysis in urine after membrane complexation and alpha spectrometry countingUranium analysis in urine after membrane complexation and alpha spectrometry counting Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2022-09-282022enA novel methodology for uranium preconcentration in urine samples was introduced. The present technique is based on the use of a selective membrane as a mean of uranium preconcentration. Various complexing membranes were prepared for this purpose. After the selection of the most efficient membrane, certain analysis factors were tested to optimize uranium membrane complexation and analysis. The equilibration time was also examined. After the separation of uranium, the radioactive sources were prepared by electrodeposition on stainless steel plates. Uranium recovery was determined by alpha spectrometry.http://creativecommons.org/licenses/by/4.0/Journal of Radioanalytical and Nuclear Chemistry3311283–288 Xarchoulakos Dimitrios C.
