2009年11月，在杭州的一次交流活动中，农村能源项目组与国家林业局竹子研究开发中心进行了深入沟通。此次交流旨在了解竹子研究开发中心在生物炭（Biochar）领域的研究进展和未来规划。生物炭作为一种新兴的农业和环境技术，引起了广泛的兴趣。生物炭是由生物质通过高温热解过程产生的碳质材料，具有稳定的物理化...
The study aimed to assess the impact of different biochars and their application rates on soil microbial and biochemical properties. An incubation experiment was conducted to evaluate the effects of biochars i.e., sugarcane filter cake biochar (SF-BC), farmyard manure biochar (FM-BC), and rice...
Manganese removal rate by various biochars (RB: rice bran, CM: chicken manure, WM: cow manure, coated biochar was produced by coating the biochar surface with iron phosphate) in Mn solution. Different letters above the bars indicate significant differences (p < 0.05) among samples based on...
Next, the adsorption of heavy metals and organic pollutants on N-doped biochars is systematically discussed. The adsorption mechanisms of contaminant removal by N-doped biochar are also clearly explained. Further, mathematical analyses of adsorption, crucial to the quantification of adsorption, process ...
The specific surface area of original DM and SS biochars were 37.4 m2 g−1 and 47.0 m2 g−1 respectively, which were within the general range of biochar as reported before33,34. Ni-loaded had little influence on the surface area. However, after microwave treatment, the spec...
Two kinds of biochars, one derived from corn straw and one from pig manure, were studied as carriers of a mutant genotype from Bacillus subtilis (B38) for heavy metal contaminated soil remediation. After amendment with biochar, the heavy metal bioavailab
Generally, biochars significantly increased the uptake of LMW-PAHs by plant but had little influence on the plant uptake of MMW-PAHs and HMW-PAHs. Three of six biochars notably increased the incremental lifetime cancer risk values based on the exposure of PAHs by vegetable consumption. Graphical...
Biochars from chlorine-rich feedstock are low in polychlorinated dioxins, furans and biphenyls 来自 dx.doi.org 喜欢 0 阅读量: 3 作者:J Grafmüller,D Rathnayake,N Hagemann,TD Bucheli,HP Schmidt 摘要: High feedstock-Cl did not increase PCDD/F and PCB in biochar above EBC thresholds.Between 1...
biochars can be high in metals such as Pb, Cd, and Cu (e.g., Bieser and Thomas2019). Alternatively, the liming properties of biochars can act to limit plant nutrient availability, particularly on soils that are already alkaline (e.g., Sarauer and Coleman2018). In addition, biochars are...
There is scant amount of literature on the structure of manure-based biochars. For wood-based materials, Gray et al. (2014) proposed a physical pore model, which describes the evolution of biochar porosity in pyrolysis. According to this model, biochar porosity consists of stable residual porosit...
