Figure 2From: Effects of aqueous complexation on reductive precipitation of uranium by Shewanella putrefaciensReductive removal of aqueous U as a function of time in contact with S. putrefaciens bacteria, at 100 μM initial U(VI) and 20 mM organic acid or 4 g/L humic acid. Analytical and sampling uncertainty is ~5 % for all trials other than humic acid. Error bars for humic acid estimate uncertainty based on replicate analyses.Back to article page
