Nano-scale metallic iron for the treatment of solutions containing multiple inorganic contaminants

Results confirmed the suitability of nano-Fe0 as a highly efficient reactive material for the aqueous removal of CrIV, CuII and UVI over a range of pH applicable to environmental waters. Insufficient MoVI removal was observed at pH >5.7, suggesting that further studies were necessary to successfully deploy INP for the treatment of geochemically complex mine water effluents. Results also indicated that uranium removal in the multi-element system was less than for the comparator containing only uranium.
