Iron-based nanoadsorbents forthe removal of metal ions from water

Considering the harmful effects of heavy metals. it is necessary to remove them from liquid wastes at least to a limit accepted by regulatorv agencies before their discharge to the environment - i.e. there isa need for. a capable, cost-effective treatment method. The application of all innovative.,. simple and low cost method was tested for the preparation of nanocrystalline iron hydroxides and oxyllydroxides; different iron precursors have been earlier used and combined to different volatile precipitating agents. The examined in the present product, akaganEite [beta-FeO(OH)], had high surface area and definite pore size distribution. Main aim of this study was to evaluate the efficiency of the prepared material in the removal of heavy metal ions, like cadmium cations and arsenate oxyan ions, metals that constitute priority pollutants. Batch and colunin experiments were conducted in current research to investioate rnetal ions removal.
