Removal of arsenic through mineral co-precipitation
The data associated with the journal article are based upon a series of laboratory experiments on coprecipitation of As(V) and As(III) in equimolar ferrous and ferric sulfate solutions through formation of sulfate green rust, goethite, and lepidocrocite: 1) XRD analysis of solids; 2) X-ray absorption spectroscopy of coprecipitates; 3) Raman spectra of coprecipitates; 4) solution chemistry of coprecipitation (pH, Eh, concentrations of ferrous and ferric ions, arsenic concentrations of the solids).
This dataset is associated with the following publication:
Su, C., and R.T. Wilkin. Removal of Arsenate and Arsenite in Equimolar Ferrous and Ferric Sulfate Solutions through Mineral Coprecipitation: Formation of Sulfate Green Rust, Goethite, and Lepidocrocite. Soil Systems. MDPI AG, Basel, SWITZERLAND, 4(68): 1-16, (2020).
