Iranian Scientists Remove 90% of Arsenic from Polluted Waters
 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. "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. Results of the research have been published on 19 July 2012 in Separation and Purification Technology, vol. 95, pp. 10-15.
