Removal of arsenic by magnetic biochar prepared from pinewood and natural hematite
Shengsen Wang,Bin Gao,Andrew R. Zimmerman,Yuncong Li,Lena Q. Ma,Willie G. Harris,Kati W. Migliaccio +6 more
TL;DR: The hematite modified biochar not only had stronger magnetic property but also showed much greater ability to remove As from aqueous solution, likely because the γ-Fe2O3 particles on the carbon surface served as sorption sites through electrostatic interactions.

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.
