Rapid and efficient removal of Pb(II) from aqueous solutions using biomass-derived activated carbon with humic acid in-situ modification.
TL;DR: This study developed an humic acid in-situ modified activated carbon adsorbent (AC-HA) for the rapid and efficient removal of Pb(II) from aqueous media, and adsorption mechanisms are discussed.
Journal ArticleDOI
Enhanced removal of Cr(VI) by biochar with Fe as electron shuttles
TL;DR: The present findings provide a potential strategy for the advanced treatment of Cr(VI) at low concentrations as well as an insight into the environmental fate of Cr (VI) and other micro-pollutants in soil or aqueous compartments containing Fe and natural or engineered carbonaceous materials.
Journal ArticleDOI
Magnetic bio-activated carbon production from lignin via a streamlined process and its use in phosphate removal from aqueous solutions.
TL;DR: The results indicate that iron species are embedded into the carbon matrix by lignin melting, suggesting that the representative MBAC product has a comparable phosphate adsorption capacity to most of the reported MBCs and MBACs.

Dynamic molecular structure of plant biomass-derived black carbon (biochar)
TL;DR: A molecular-level assessment of the physical organization and chemical complexity of biomass-derived chars and, specifically, that of aromatic carbon in char structures suggests the existence of four distinct categories of char consisting of a unique mixture of chemical phases and physical states.
