Impact of various amendments on immobilization and phytoavailability of nickel and zinc in a contaminated floodplain soil
TL;DR: In this article, a greenhouse pot experiment was established with a contaminated agricultural floodplain soil and the soil was treated with activated carbon (AC), bentonite (BE), biochar (BI), cement bypass kiln dust (CBD), chitosan (CH), coal fly ash (FA), limestone (LS), nano-hydroxyapatite (HA), organo-clay (OC), sugar beet factory lime (SBFL), and zeolite (Z) with an application rate of 1% (0.2% for HA) and cultivated by rapeseed

TL;DR: CFB500 was a promising material for the remediation of Pb-contaminated aqueous environments (e.g., wastewater) and the contribution of binding sites for Pb2+ sorption was ascribed to the outer-wall of carbon skeleton of CFB500, which was stronger than that provided by the mineral oxide aggregate and phytoliths.

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.
