MOFs that remove and reduce hexavalent chromium yield drinkable water
Tests using river water prove system has a high selectivity for Cr(vi), even in the presence of large quantities of competing cations
Scientists have made a material that can selectively remove toxic hexavalent chromium ions (Cr(vi)) from water. The metal–organic frameworks (MOFs) also act as photocatalysts that reduce the Cr(vi) to less harmful Cr(iii) ions when illuminated with light, simultaneously removing and treating the pollutant and making contaminated water drinkable.
