文摘

First prolonged kinetics study of uranium to halophilic archaea was performed. An atypical time-dependent bioassociation behavior of uranium was observed. Unique combination of spectroscopic and microscopic methods was used. In situ ATR FT-IR showed association of U(VI) to phosphoryl and carboxylate groups. Time-dependent changes of U(VI) localization could be monitored by SEM/EDX.
