TL;DR: Overall, the sorption capacity of CFBs pyrolyzed at 300°C substantially increased for Pb2+ with ammonia and nitric acid modification, however, these chemical modifications did not improve the Sorption of Pb on CFBspyrolyzing at temperatures ≥500°C, thereby highlighting a temperature dependent response of chemically modified biochars to Pb sorption in this study.

TL;DR: In this paper, the role of GRSP in sequestering Pb and Cd was investigated in an in situ field experiment and the effect of metal sequestration on GRSP was also investigated.

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.

TL;DR: Resistance of biochars to chemical treatment increased with pyrolysis temperature, indicating that resistance of bio chars tochemical treatment increased in aqueous solutions.

TL;DR: Evidence is provided that, in response to Pb and Cr stress, pakchoi uses cell walls and vacuoles to reduce the transport of these heavy metals through the plant, as well as restrict transport from the root to the stem.
