TLDR
In this article, chitosan-modified biochars were synthesized in efforts to produce a low-cost adsorbent for heavy metal environmental remediation, and the results showed that the coating of chitosa on biochar surfaces could improve its performance as a soil amendment or an adorbent.About:

Chemical Treatments for Biochar Modification: Opportunities, Limitations and Advantages
TL;DR: The biochar can be utilized as an efficient adsorbent for contaminated soil and water, but the practical implementation of biochar in immobilization and removal of contaminants need some modifications as discussed by the authors .

A system and method for water treatment
TL;DR: In this article, the authors describe a system for treating water, which comprises one or more inlets for introducing biochar and polyamine to the water, such as a biochar inlet and a polyamine inlet, or any combination thereof.

A review of biochar and its use and function in soil
TL;DR: The potential to sequester carbon as thermally stabilized (charred) biomass using existing organic resource is estimated to be at least 1 Gt/yr − 1 and biochar, defined by its useful application to soil, is expected to provide a benefit from enduring physical and chemical properties.

A review of biochars’ potential role in the remediation, revegetation and restoration of contaminated soils
Luke Beesley,Eduardo Moreno-Jiménez,Jose L. Gomez-Eyles,Eva Harris,Brett Robinson,Tom Sizmur +5 more
TL;DR: Specific mechanisms of contaminant-biochar retention and release over time and the environmental impact of biochar amendments on soil organisms remain somewhat unclear but must be investigated to ensure that the management of environmental pollution coincides with ecological sustainability.

Positive and negative carbon mineralization priming effects among a variety of biochar-amended soils.
TL;DR: In an effort to better understand the interaction of pyrogenic C and soil organic matter (OM), a range of Florida soils were incubated with a variety of laboratory-produced biochars and CO 2 evolution was measured over more than one year as discussed by the authors.
