Journal ArticleDOI
Pyrolysis temperature influences the characteristics of rice straw and husk biochar and sorption/desorption behaviour of their biourea composite.
TL;DR: Microporosity, cation exchange capacity and functional groups primarily carboxyl and keto group, played key role in sorption/desorption pattern of biourea with slow release kinetics.
Journal ArticleDOI
Efficient removal of diclofenac and cephalexin from aqueous solution using Anthriscus sylvestris-derived activated biochar.
TL;DR: This study provides a feasible approach to synthesize activated biochar that can minimize pharmaceuticals pollution in water bodies and plays a key role in adsorption of both adsorbates by ACT-B.
Journal ArticleDOI
Novel Biochar-Plant Tandem Approach for Remediating Hexachlorobenzene Contaminated Soils: Proof-of-Concept and New Insight into the Rhizosphere.
TL;DR: The results from this study suggest that the biochar-plant tandem approach could be an effective strategy for remediating soils contaminated with semi/volatile organic contaminants.

Mobility of Pb, Zn, Ba, As and Cd toward soil pore water and plants (willow and ryegrass) from a mine soil amended with biochar
Marie-Paule Norini,Hugues Thouin,Florie Miard,Fabienne Battaglia-Brunet,Pascale Gautret,Régis Guégan,Lydie Le Forestier,Domenico Morabito,Sylvain Bourgerie,Mikael Motelica-Heino +9 more
TL;DR: By improving major ions available in mine soil, BC improved the lifetime of plants and enhanced their growth and the physicochemical parameters and concentrations of the different metal(loid)s in both SPW and in plant tissues of willow and ryegrass highlight the importance of BC for SPW properties.
Journal ArticleDOI
Field experiment on the effects of sepiolite and biochar on the remediation of Cd- and Pb-polluted farmlands around a Pb–Zn mine in Yunnan Province, China
TL;DR: It is revealed that sepiolite increases soil pH and decreases Cd bioavailability in farmland soils around the Pb–Zn mine and biochar increases the contents of available nutrients in farmland soil and the maize yield.

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
Ameliorating physical and chemical properties of highly weathered soils in the tropics with charcoal – a review
TL;DR: In this paper, the authors reviewed the available information about the physical and chemical properties of charcoal as affected by different combustion procedures, and the effects of its application in agricultural fields on nutrient retention and crop production.
Journal ArticleDOI
Dynamic molecular structure of plant biomass-derived black carbon (biochar)
TL;DR: A molecular-level assessment of the physical organization and chemical complexity of biomass-derived chars and, specifically, that of aromatic carbon in char structures suggests the existence of four distinct categories of char consisting of a unique mixture of chemical phases and physical states.
