Decreasing cadmium uptake of rice (Oryza sativa L.) in the cadmium-contaminated paddy field through different cultivars coupling with appropriate soil amendments
TL;DR: Wang et al. as mentioned in this paper used four soil amendments (e.g., lime, biochar, soil conditioner, and seaweed organic fertilizer) combined with two rice cultivars (Yongyou17, YY-17; and Xiushui09, XS-09) to evaluate the efficacy of safe utilization in a slightly moderately Cd-contaminated paddy soil.
Journal ArticleDOI
Wood-derived-biochar combined with compost or iron grit for in situ stabilization of Cd, Pb, and Zn in a contaminated soil
TL;DR: In situ stabilization of Cd, Pb, and Zn in an Austrian agricultural soil contaminated by atmospheric depositions from a smelter plant was assessed with a pine bark chip-derived biochar, alone and in combination with either compost or iron grit.
Journal ArticleDOI
Effects of copyrolysis of sludge with calcium carbonate and calcium hydrogen phosphate on chemical stability of carbon and release of toxic elements in the resultant biochars.
TL;DR: Results indicated that the copyrolysis of sludge with phosphate and carbonate, especially phosphate, were effective methods to prepare the sludge-based biochars with immobilized toxic elements and enhanced chemical stability of carbon.
Journal ArticleDOI
Selective adsorption of organic pigments on inorganically modified mesoporous biochar and its mechanism based on molecular structure.
TL;DR: The characterization results demonstrated that Fe3O4 particles successfully attached to the surface of biochar after modification, and the as-prepared materials showed a better selective adsorption effect on the cationic pigments.

Impacts of carbonization temperature on the Pb(II) adsorption by wheat straw-derived biochar and related mechanism
Yaoyao Cao,Guanghui Shen,Yang Zhang,Chongfeng Gao,Yanfei Li,Peizhen Zhang,Weihua Xiao,Lujia Han +7 more
TL;DR: The EDX, XRD, and FTIR analysis results further clarified that ion exchange and precipitation were the main adsorption mechanisms for Pb(II) advertisersorption by wheat straw-derived biochar.

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.

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.

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.
