Nanostructured Iron-Based Sorption Materials for Drinking Water andWastewater Treatment

The paper analyzed the usage and efficiency of different types (zero valent iron, oxides, hydroxides, oxyhydroxides, composites, etc.) of nanostructured ironcontaining sorption materials in water treatment. It was noted that iron-based adsorbents are effective in removal wide range of pollutants (various organic compounds, arsenites, arsenates, phosphates, heavy metal ions, etc.). Nanoparticles of zero valent iron are one of the most popular iron-based nanomaterials for water treatment. There a lot of approaches to obtain these nanoparticles, including top-down (processing micro- or millimeter-sized iron) and bottom-up (using iron-containing compounds as starting materials) synthetic methods. Iron-based nanostructured materials are often used in the form of different doped oxides or nanocomposites with organic or inorganic substances. In the paper various methods of synthesis and application of nanostructured iron-based sorption materials are observed.
