Adsorption of Fluoride by Aligned Carbon Nanotubes Supported Ceria Nanoparticles


Article Preview

Ceria nanoparticles supported on aligned carbon nanotubes (CeO2/ACNTs), a novel adsorbent for fluoride from drinking water, were prepared by chemical reaction of CeCl3 with NaOH on aligned carbon nanotube solution and subsequent heat treatment. The best fluoride adsorption effect of CeO2/ACNTs occurs at pH 4.0 ~ 9.0. The largest adsorption capacity of CeO2/ACNTs reaches 33.7 mg g-1 at an equilibrium fluoride concentration of 18.0 mg l-1 at pH 7.0. The experiment results suggest that CeO2/ACNTs have great potential applications in environmental protection.
