Abstract

The invention discloses methods of preparing Iron-modified nanostructured silica beads and iron-modified nanosilica powder. The resulting composition is used as heavy metal adsorbents in the removal of arsenic from contaminated water. These materials allow the remediation of arsenic contaminated groundwater using low cost, locally available, and sustainable nanomaterials.
