Abstract:
Iranian researchers from Bu-Ali Sina University, Yazd University and Hamedan University of Medical Sciences succeeded in removing arsenic from polluted waters by using calcium peroxide nanoparticles.

Iranian Scientists Remove 90% of Arsenic from Polluted Waters

Tehran, Iran | Posted on November 8th, 2012

According to the results, these nanoparticles can remove 90% of arsenic from polluted water due to their high oxidation power and their harmlessness.

"The goal of the research was to present a useful, simple, and cost-effective method in order to reduce arsenic concentration in polluted waters through the synthesis of calcium peroxide nanoparticles. In this research, a method was presented, which according to the final results, is one of the newest methods in the world," Dr. Hossein Banejad, one of the researchers of the plan, stated about the research.

According to Dr. Banejad, the removal of arsenic from waters polluted with this element by using calcium peroxide nanoparticles was the most important characteristic of the research. Calcium peroxide nanoparticles oxidized arsenic from a very toxic form (five capacities arsenic) to three capacities arsenic with much lower toxicity due to their high oxidation power. Arsenic is finally separated from the environment due to the formation of a complex and due to the low activity of arsenic and its high adsorption on various surfaces. A final 90% removal of the pollutant is obtained at the end of the experiment.

The method is classified among the high performance methods in the removal of hazardous materials in water resources and industrial wastewater. The most noticeable feature of the method is the ability of arsenic removal, as a toxic and hazardous material, from surface and underground waters without the need for specific chemical components.

Results of the research have been published on 19 July 2012 in Separation and Purification Technology, vol. 95, pp. 10-15.
