Macro- and micro-scale studies on U(VI) immobilization in hardened cement paste

Autor: D. Kunz, Nathalie Macé, Rainer Dähn, Jan Tits, Erich Wieland

Wet chemistry and synchrotron-based (micro-)spectroscopic investigations have been carried out to determine the uptake and speciation of U(VI) in hardened cement paste (HCP). The wet chemistry experiments included kinetic studies and the determinatio
