BACKGROUND
In this study, a defective biochar with honeycomb‐like porous structure (BC‐PH) was successfully prepared by the activation of pristine biochar derived from bamboo shoot shell with the chemical reagent KOH, and was applied to selectively separate ReO4− (a chemical analogue for radioactive TcO4−) from acidic solutions.
RESULTS
The diffusion, mass transfer and recovery for ReO4− could...
