MODIFIED NANOSTRUCTURED SILICA MATERIALS FOR HEAVY METAL REMOVAL FROM CONTAMINATED WATER AND THE METHODS OF PRODUCTION THEREOF

摘要

This invention discloses the 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.
