Waste water of steel processing plant may contain a significant amount of heavy metal ions and thus pose serious environmental and health threat if not properly treated. Traditionally, such waste water is treated by simple chemical precipitation which may result in a large amount of solid waste with very little recovery value, crowding the very limited space for landfills. To reduce the solid waste and to recover the metallic elements in the waste water, nanostructured metal oxides were synthesized from the waste water of a steel processing plant and tested for arsenic adsorption. By controlling the synthetic chemistry and processing conditions, arsenic adsorbents with very high adsorption capacity were developed. The outlook for extending the lab study to large scale commercial applications is discussed.
