Abstract
The removal of arsenic from reservoirs is a matter of great concern in many parts of the world. Since adsorption is one of the most effective methods for treating arsenic-containing media, iron oxide nanorods were prepared using cellulose nanocrystals (CNs) as a template to remove this harmful metal from aqueous solutions. X-ray diffraction (XRD) analysis showed that Fe(OH)3 was formed in the initial stage of the hydrothermal reaction, and Fe(OH)3 was transformed into Fe2O3 as the hydrothermal reaction proceeded. Transmission electron microscopy (TEM) analysis showed that the length of the iron oxide nanorods was nearly 200 nm, and the width was 10 nm. Moreover, adsorption property studies showed that the maximal amount of As(III) and As(V) adsorption, corresponding to levels of 13.866 mg/g and 15.712 mg/g, occurred at pH levels of 7 and 3, respectively. The adsorption process conformed to the quasi-second-order kinetic and Langmuir adsorption isotherm models, indicating that the adsorption process consists of a chemical adsorption of monolayers. The results indicate that this composite can be used as a potential adsorbent for treatment of water containing harmful substances.
