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:

Effect of acid modified biochar on the growth and essential and non-essential element content of bean, chickpea, soybean, and maize grown in calcareous soil.
TL;DR: In this article, both biochar and modified biochar (MBC) were applied at a rate of 10 g kg−1 to maize and chickpea plants, respectively.

Removal of nitrate from constructed wetland in winter in high-latitude areas with modified hydrophyte biochars
TL;DR: In this article, the authors investigated the removal of nitrate from aqueous solution and wastewater by modified hydrophyte biochars from constructed wetlands in high-latitude areas.
Journal ArticleDOI
Characteristics and Mechanism of Pb2+ Adsorption From Aqueous Solution Onto Biochar Derived From Microalgae and Chitosan-Modified Microalgae
TL;DR: In this paper, two new types of microalgae biochar are developed as adsorbent material using Clostridium and adding chitosan as a modifier at different stages of its preparation.
Journal ArticleDOI
Chitosan-Modified Biochar and Unmodified Biochar for Methyl Orange: Adsorption Characteristics and Mechanism Exploration
TL;DR: In this article , shrimp shell-derived chitosan (CS) and rice husk-derived biochar (RHB) were produced; CS and RHB were then used to synthesize CHI modified biochar hydrogel beads, and the results showed that the MO adsorption process was strongly pH-dependent.
Journal ArticleDOI
UV/O 3 Preirradiated Cotton Fabric-Containing Chitosan for Effective Removal of Heavy Metals
TL;DR: In this article, the effect of Ultra-Violet/Ozone (UV/O3) irradiation of cotton fabrics on their interaction with chitosan/citric acid based formulation and, the onset of this on the ability of treated fabrics to remove heavy metal ions from their aqueous solutions.

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.

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.
