Mechanisms of metal sorption by biochars: Biochar characteristics and modifications
Hong-Bo Li,Xiaoling Dong,Evandro B. da Silva,Letuzia M. de Oliveira,Yanshan Chen,Lena Q. Ma,Lena Q. Ma +6 more
TL;DR: This review summarizes the characteristics of biochar (e.g., surface area, porosity, pH, surface charge, functional groups, and mineral components) and main mechanisms governing sorption of As, Cr, Cd, Pb, and Hg by biochar and includes competitive sorption mechanisms of co-existing metals.
Journal ArticleDOI
Biochar physicochemical properties: pyrolysis temperature and feedstock kind effects
TL;DR: In this article, the impact of pyrolysis temperature and the type of biomass on the physicochemical characteristics of biochar and its impact on soil fertility is discussed, and a review succinctly presents the impact.
Journal ArticleDOI
Physico-chemical properties and microbial responses in biochar-amended soils: Mechanisms and future directions
TL;DR: In this article, a meta-analysis revealed that slow pyrolyzed biochars produced from various feedstocks at temperatures from 300°C to 600°C consistently increased some physico-chemical properties (i.e., pH, cation exchange capacity and aggregation) and microbial parameters (e.g., abundance and community structure of microorganisms) in a vast number of soils during short (≤90 days) laboratory incubations and longer (1-3 years) field studies.

Properties of biochar
Kathrin Weber,Peter Quicker +1 more
TL;DR: In this article, a large number of experiments on biochar production is presented to give a general overview of the properties that can be achieved by feedstock selection and process design, including torrefaction as well as slow pyrolysis at high temperatures.

Biochar effects on soil biota – A review
Johannes Lehmann,Matthias C. Rillig,Janice E. Thies,Caroline A. Masiello,William C. Hockaday,David E. Crowley +5 more
TL;DR: A review of the literature reveals a significant number of early studies on biochar-type materials as soil amendments either for managing pathogens, as inoculant carriers or for manipulative experiments to sorb signaling compounds or toxins as mentioned in this paper.
Journal ArticleDOI
Some aspects of the surface chemistry of carbon blacks and other carbons
TL;DR: In this paper, a review of the surface chemistry of carbon blacks and other activated carbons is given, focusing on surface oxides with emphasis on the chemical methods used in the assessment and identification of surface functional groups.
Journal ArticleDOI
A handful of carbon
TL;DR: On the climate change mitigation front, the incorporation of ‘biochar’ into the soil is one idea gaining support, and Johannes Lehmann argues that trapping biomass carbon in this way is more effective than storing it in plants and trees that will one day decompose.

Agronomic values of greenwaste biochar as a soil amendment
TL;DR: In this article, a pot trial was carried out to investigate the effect of biochar produced from greenwaste by pyrolysis on the yield of radish and the soil quality of an Alfisol.

The forms of alkalis in the biochar produced from crop residues at different temperatures
TL;DR: The forms of alkalis of the biochars produced from the straws of canola, corn, soybean and peanut at different temperatures (300, 500 and 700°C) were studied by means of oxygen-limited pyrolysis and it was suggested that carbonates were the major alkaline components in theBiochars generated at the high temperature.
