Selective removal of cesium ions from aqueous solutions by zinc hexacyanoferrate functionalized magnetic carbon nanotube composites as adsorbent

Zinc hexacyanoferrate functionalized magnetic carbon nanotube composites were synthesized to be used as adsorbents for the selective removal of Cs. The synthesized adsorbents exhibited a high adsorption capacity that could be successfully improved by increasing the loading of zinc hexacyanoferrate, which plays a major role in selectively adsorbing and removing Cs from the adsorbent surface. Although the saturation magnetization value for the synthesized adsorbents decreased with increasing zinc hexacyanoferrate loading, the adsorbents could be sufficiently separated by using a permanent magnet.
