A pilot study on the effect of desferrioxamine B on uranium VI precipitation and dissolution in pH 11.5, 0.1 M NaCl solutions

Abstract A pilot study investigating the possible role of desferrioxamine B (DFOB) to prevent U VI precipitation in alkaline NaCl solutions was carried out. Desferrioxamine is a hydroxamate siderophore occurring naturally environment. The can possibly mobilize from wide range sources such as mine tailings, contaminated land and radioactive waste storage disposal facilities. results series batch experiments covering concentrations over relevant time scales (3 days 2 months) show that DFOB quantitatively ≥ 0.2 μm precipitates when 130 µM 420 present solution. impact minimized its concentration decrease below 10 µM, suggesting these ligands will have less mobilizing effect on uranium geological facility if oxidation state.
