Adsorption performance of U(VI) by amidoxime-based activated carbon

We present a simple strategy for preparing amidoxime modified activated carbon. The composition and morphology of the materials have been confirmed via powder XRD, BET, TGA, SEM and FT-IR studies. Batch adsorption experiment were exploited to explore adsorption performance of U(VI) by amidoxime-based activated carbon. The adsorption capacity of activated carbon was significantly improved after the modification by amidoxime, the amidoxime-based activated carbon was a possible adsorbent for adsorbing U(VI). This study reveals that with a facile synthesis and low-cost, amidoxime-based activated carbon can be regarded as a promising material for uranium-containing wastewater treatment.
