Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    Data for Evolving Mineralogy and Reactivity of Hematite-Coated Sands During Reduction by Fe(II) of 4-Chloronitrobenzene in Column Reactors
    (2024-10-14) Harris, Celina M; Soroush, Adel; Hildebrandt, Alanna M; Amen, Kamilah Y; Corcoran, Louis G; Feinberg, Joshua M; Arnold, William A; Penn, R Lee; arnol032@umn.edu; Arnold, William; Arnold, Penn and Feinberg labs at the University of Minnesota
    This study explores the reaction of contaminants mediated by iron oxide minerals in a column reactor that simulated iron reducing groundwater conditions. Reaction of the model nitroaromatic pollutant with hematite-coated sand in column reactors leads to growth of goethite and evolving reactivity due to changes in accessible surface area. Data collected include concentrations of the model pollutant (4-chloronitrobenzene) and its reaction product, the amount of new iron oxide mineral formed, and chloride concentrations in tracer studies.
