Synthesis of sandwich-like Mn(3)O(4)@reduced graphene oxide nano-composites via modified Hummers' method and its application as uranyl adsorbents

Efficient and sustainable remediation technologies for uranium have recently been gaining more and more interest. Adsorption techniques are facile, effective and universal for kinds of heavy metal ions. In this paper, sandwich-like Mn(3)O(4)@reduced graphene oxide (Mn(3)O(4)@G) nano-composites were...

description Efficient and sustainable remediation technologies for uranium have recently been gaining more and more interest. Adsorption techniques are facile, effective and universal for kinds of heavy metal ions. In this paper, sandwich-like Mn(3)O(4)@reduced graphene oxide (Mn(3)O(4)@G) nano-composites were prepared facilely and greenly by adding NaOH solution into crude graphite oxide suspension prepared via the Hummers' method to modify the pH. The Mn(3)O(4)@G nanocomposites possess a reasonable maximum equilibrium adsorption quantity 195.6 mg [U] g(−1). Moreover, the magnetism of Mn(3)O(4)@G makes it easy to remove Mn(3)O(4)@G from water by strong magnet field.
