Zusammenfassung

In this project we aim to develop a low-cost technology to remove ionic constituents from raw waters such as arsenic species. The proposed technology is based on the reactivity of schwertmannite, an oxyhydroxosulfate of the mean stochiometry Fe8O8(OH)6SO4 (molar mass 772.89 g/mol). This mineral typically forms in acidic and sulfate rich mine waters as a secondary mineral upon oxidation of Fe(II) in a biologically mediated process. Schwertmannite can be generated in a biotechnological process after aeration of mining process waters. It forms surface-rich aggregates of needle-like nanocrystals. It rapidly transforms into ferric hydroxides of high specific surface area once exposed to water containing at least some alkalinity. Our rationale follows the concept to make use of this transformation reaction by adding biosynthesized schwertmannite to contaminated raw waters where it generates a large sorption capacity to remove the pollutants (Peiffer et al., 2008).
