Temperature-dependent luminescence spectroscopic and mass spectrometric investigations of U(VI) complexation with aqueous silicates in the acidic pH-range

Autor: Henry Lösch, Manuel Raiwa, Norbert Jordan, Michael Steppert, Robin Steudtner, Thorsten Stumpf, Nina Huittinen

Publikováno v: Environment International, Vol 136, Iss , Pp - (2020)

In this study the complexation of U(VI) with orthosilicic acid (H4SiO4) was investigated between pH 3.5 and 5 by combining electrospray ionization mass spectrometry (ESI-MS) and laser-induced luminescence spectroscopy. The ESI-MS experiments performe

Journal of hazardous materials : environmental control, risk assessment, impact and management

Microscopic fuel fragments, so-called “hot particles”, were released during the 1986 accident at the Chornobyl nuclear powerplant and continue to contaminate the exclusion zone in northern Ukraine. Isotopic analysis can provide vital information

Journal of radioanalytical and nuclear chemistry : an international journal dealing with all aspects and applications of nuclear chemistry

In this work, uranium-and plutonium-baring particles were produced by fast iron co-precipitation for the purpose of creating homogeneous multi-element standards. A set of single isolated particles showing no inhomogeneities in the element distributio

Influence of the hyperfine structure on plutonium in resonant laser-SNMS

Autor: Hauke Bosco, Nina Kneip, Klaus Wendt, Martin Weiss, Clemens Walther, Manuel Raiwa

Publikováno v: Hyperfine interactions 241 (2020), Nr. 1
Hyperfine interactions

Resonance ionization mass spectrometry is an ultra-sensitive and highly element selective tool for spectroscopy, ionization and detection of atoms and thus enables rare isotope determination. In combination with spatially resolved sputtering of neutr
