heal.abstract	The objective of this study was the evaluation of elemental iron for the remediation of groundwater contaminated by uranium (VI). The study was focused on the effect of different conditions on the removal of uranium by elemental iron, as well as on the determination of the predominant reaction mechanisms. The conditions applied where either atmospheric or geochemical (presence of excess CO32-) while the presence of SO42- ions was also studied. The results indicated that under atmospheric conditions, almost 98% of U(VI) is removed when the pH is in the neutral and alkaline regions, while the acidic pH reduces the removal to about 82%. Under geochemical conditions the uranium (VI) removal is decreased while in the presence of SO42- ions it does not affected at all. The mechanism of uranium (VI) uptake by elemental iron was attributed to the precipitation of uranyl hydroxides along with the sorption of uranyl ions on the iron hydroxides.	en
