Sorption of Strontium by Bacteria, Fe(III) Oxide, and Bacteria−Fe(III) Oxide Composites

This study provides the first quantitative comparison of the sorptive capacities of a bacteria−Fe oxide composite to its individual components. These results have enormous significance for understanding the fate and transport of inorganic contaminants in natural aqueous environments where heterogeneous bacteria−oxide composite solids are commonly found. We quantify Sr2+ sorption to the bacteria Shewanella alga, Shewanella putrefaciens, …
