Content and morphology of lead remediated by activated carbon and biochar: A spectral induced polarization study
TL;DR: The observed SIP responses of both AC and biochar are two orders of magnitude higher than those of typical natural soils or silica materials, which is an additional advantage for the field application of SIP technique in PRB scenarios.

Physisorption Hysteresis Loops and the Characterization of Nanoporous Materials
TL;DR: In this article, a review of the IUPAC classification of adsorption hysteresis loops is presented, concluding that there is no immediate need to change the classification of physisorption isotherms and hystereis loops and that a carefully regulated application of DFT in place of a classical procedure such as the well-known Barrett-Joyner-Halenda (BJH) method is proposed.

Adsorption of cadmium(II) from aqueous solution by surface oxidized carbon nanotubes
TL;DR: In this article, carbon nanotubes (CNTs) were oxidized with H2O2, KMnO4, and HNO3, and the experimental results suggest that cadmium(II) adsorption capacities for three kinds of oxidized CNTs increase due to the functional groups introduced by oxidation compared with the as-grown CNT.
