An Assessment of U(VI) removal from groundwater using biochar produced from hydrothermal carbonization
TLDR
The results of the column study indicate that biochar could be used as an effective adsorbent for U(VI), as a reactive barrier medium, and efficient in removing U( VI) from groundwater.About:

Bio-energy in the black
TL;DR: The precise half-life of biochar is still disputed, and this will have important implications for the value of the technology, particularly in carbon trading as mentioned in this paper, and it is not clear under what conditions, and over what period of time, biochar develops its adsorbing properties.
