Iron-based nanoadsorbents for the 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 regulatory agencies before their discharge to the environment – i.e. there is a need for a capable, cost-effective treatment method. The application of an innovative, simple and low cost method was tested for the preparation of nanocrystalline iron hydroxides and oxyhydroxides; different iron precursors have been earlier used and combined to different volatile precipitating agents. The examined in the present product, akaganéite [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 oxyanions, metals that constitute priority pollutants. Batch and column experiments were conducted in current research to investigate metal ions removal.
