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:

Biosorption of cadmium(II), lead(II) and cobalt(II) from aqueous solution by biochar from cones of larch (Larix decidua Mill. subsp. decidua) and spruce (Picea abies L. H. Karst)
Bogdan Saletnik,Grzegorz Zaguła,Dorota Grabek-Lejko,Idalia Kasprzyk,Marcin Bajcar,Maria Czernicka,Czesław Puchalski +6 more
TL;DR: In this article, the authors used biochar obtained from cones of larch (Larix decidua mill) and spruce (Picea abies L. H. subsp. Karst) to remove Cd2+, Pb2+ and Co2+ in aqueous solutions.

Chitosan-ZnO decorated Moringa oleifera seed biochar for sequestration of methylene blue: Isotherms, kinetics, and response surface analysis
TL;DR: In this paper , Moringa oleifera seeds-derived biochar (B) was modified using chitosan-ZnO (CZ), denoted as CZ-B, applied for the removal of methylene blue (MB) dye in an aqueous solution.
Journal ArticleDOI
Adsorptive Removal of Manganese Ions from Polluted Aqueous Media by Glauconite Clay-Functionalized Chitosan Nanocomposites
TL;DR: In this article, the adsorption properties of the G clay and its nanocomposites toward the removal of Mn(II) ions from polluted aqueous media as well as the adaption mechanism were explored using a batch technique.

Effectiveness of Biochar Obtained from Corncob for Immobilization of Lead in Contaminated Soil
Alfonso Rodriguez,Alfonso Rodriguez,Daniela Lemos,Yessika T Trujillo,Julián G Amaya,Laura D Ramos +5 more
TL;DR: Although the lead immobilization in soil was positive for both cases, the use of soil with high concentrations of lead does not indicate biochar's effectiveness for purposes of comparison with the current United States Environmental Protection Agency limit value (400 ppm for bare soil in urban play areas).
Journal ArticleDOI
Sorption of imazapic and imazapyr herbicides on chitosan-modified biochars
TL;DR: In this paper, two biochars were produced separately from oil palm empty fruit bunches and rice husk biomasses and then modified with chitosan in a nitrogen gas environment.

Bio-char sequestration in terrestrial ecosystems - a review
TL;DR: The application of bio-char (charcoal or biomass-derived black carbon (C)) to soil is pro- posed as a novel approach to establish a significant, long-term, sink for atmospheric carbon dioxide in terrestrial ecosystems.

Johannes Lehmann,Stephen Joseph +1 more
TL;DR: In this article, Flannery presented a Biochar Classification and Test Methods for determining the quantity of Biochar within Soils and its effect on Nutrient Transformations and Nutrient Leaching.
Book ChapterDOI
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.
