Data for Evolving Mineralogy and Reactivity of Hematite-Coated Sands During Reduction by Fe(II) of 4-Chloronitrobenzene in Column Reactors

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.
