DOI: 10.3390/nano12030326
Abstract: Iron oxides/oxyhydroxides, namely maghemite, iron oxide-silica composite, akaganeite, and ferrihydrite, are studied for AsV and AsIII removal from water in the pH range 2–8. All sorbents were characterized for their structural, morphological, textural, and surface… read more here.

DOI: 10.5006/2162
Abstract: Iron (Fe) oxides/oxyhydroxides in drinking water distribution systems (DWDS), produced by electrochemical, chemical, and biological reactions, can adsorb toxic metal ions, including strontium, lead, arsenic, and vanadium that, if desorbed, generate pulses of drinking water… read more here.
