TLDR
Lead sorption capacity and mechanisms by sludge-derived biochar (SDBC) were investigated to determine if treatment of acid mine drainage containing metals with SDBC is feasible, and may suggest that the application ofSDBC is a feasible strategy for removing metal contaminants from acid solutions.About:

Dairy-manure derived biochar effectively sorbs lead and atrazine.
TL;DR: Results from this study indicated that dairy manure can be converted into value-added biochar as effective sorbent for metal and/or organic contaminants.
Journal ArticleDOI
Compositions and sorptive properties of crop residue-derived chars.
TL;DR: Chars originating from the burning or pyrolysis of vegetation may significantly sorb neutral organic contaminants (NOCs) and appear to have a higher surface affinity for a polar solute (nitrobenzene) than for a nonpolar Solute (benzenes), the difference being related to the surface acidity/basicity of the char samples.
Journal ArticleDOI
Characterisation and evaluation of biochars for their application as a soil amendment
TL;DR: In this article, the authors used X-ray diffraction analysis to identify the presence of whewellite in E. saligna biochars produced at 400°C and 550°C with activation.
Journal ArticleDOI
Influence of pyrolysis temperature on production and nutrient properties of wastewater sludge biochar.
TL;DR: Investigation of the influence of pyrolysis temperature on production of wastewater sludge biochar and the properties required for agronomic applications found biochar produced at low temperature was acidic whereas at high temperature it was alkaline in nature.

FTIR spectrophotometry, kinetics and adsorption isotherms modeling, ion exchange, and EDX analysis for understanding the mechanism of Cd2+ and Pb2+ removal by mango peel waste.
TL;DR: EDX analysis of MPW before and after metal sorption and release of cations from MPW with the corresponding uptake of Cd(2+) and Pb(2+) revealed that the main mechanism of sorption was ion exchange.
