Abstract:

In this research "MnO2/MWCNT" nanocomposite was prepared firstly and then it was used as an adsorbent for Cr+3 ions removal from aqueous solutions. Our results showed that the prepared nanocomposite from modified multi-wall carbon nanotube and MnO2 has a good capacity for Cr+3 removal from aqueous solution. Morphology and Crystallinity of the modified MWCNT before and after deposition on MnO2 were examined by SEM and XRD. In turn, the experimental results were examined according to the Langmuir, Freundlich and Temkin Isotherms and Freundlich isotherm represented our experimental results.
