Summary: | The adsorption of uranium(VI) onto bamboo (
Acidosasa longiligula
) shoot shell biochar (ASBC) was investigated in batch experiments and the adsorbent was characterized by two-dimensional infrared correlation spectroscopy. The adsorption equilibrium data followed the Langmuir isotherm with maximum adsorption capacity of 32.3 mg g
−1
at 298 K. The biochar exhibited a high selectivity for uranium(VI) against Na
+
ions. Desorption rate of higher than 90% was obtained over three adsorption–desorption cycles. The adsorption mechanisms of uranium(VI) by ASBC involved surface complexation and cation–π interaction. Results suggested that ASBC was a low-cost and potential adsorbent for uranium(VI) isolation from aqueous solution. |
