TLDR
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.About:

Sabry M. Shaheen,Sabry M. Shaheen,Nabeel Khan Niazi,Nabeel Khan Niazi,Noha E.E. Hassan,Irshad Bibi,Irshad Bibi,Hailong Wang,Daniel C.W. Tsang,Yong Sik Ok,Nanthi Bolan,Jörg Rinklebe,Jörg Rinklebe +12 more
TL;DR: In this paper, the potential use of wood-based biochar (WB) for the removal of potentially toxic elements (PTEs) from water and wastewater has been discussed, and a review demonstrates the overarching scientific opportunities for a comprehensive understanding of using WB as an emerging biosorbent and a promising low-cost and effective material for the remediation of contaminated water.

The adsorption of gases on plane surfaces of glass, mica and platinum.
TL;DR: In this article, the absorption index at the wave length of the band maximum was found to be proportional to the total concentration of metal at shorter wave lengths, however, deviations were observed, the absorption increasing more rapidly with concentration than Beers' law would demand.
