Journal ArticleDOI
Organic and inorganic contaminants removal from water with biochar, a renewable, low cost and sustainable adsorbent--a critical review.
TL;DR: A review of recent applications of biochars, produced from biomass pyrolysis (slow and fast), in water and wastewater treatment, and a few recommendations for further research have been made in the area of biochar development for application to water filtration.
Journal ArticleDOI
Lignocellulosic biomass pyrolysis: A review of product properties and effects of pyrolysis parameters
TL;DR: In this paper, a general summary of the properties of pyrolytic products and their analysis methods is given, as well as a review of the parameters that affect the process and a summary of current state of the art.
Journal ArticleDOI
Application of biochar for the removal of pollutants from aqueous solutions.
TL;DR: An overview of biochar production technologies, biochar properties, and recent advances in the removal of heavy metals, organic pollutants and other inorganic pollutants using biochar is provided.
Journal ArticleDOI
Pharmaceuticals of Emerging Concern in Aquatic Systems: Chemistry, Occurrence, Effects, and Removal Methods.
TL;DR: Adsorption technologies are a low-cost alternative, easily used in developing countries where there is a dearth of advanced technologies, skilled personnel, and available capital, and adsorption appears to be the most broadly feasible pharmaceutical removal method.

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.

Surface Charge and Solute Interactions in Soils
TL;DR: In this paper, the authors discuss the various methods used to measure surface charge and factors affecting this charge and make an attempt to compare current theories on the nature of the charged solid surface-solution interface.
Journal ArticleDOI
High-Temperature Pyrolysis of Blended Animal Manures for Producing Renewable Energy and Value-Added Biochar
TL;DR: In this paper, a commercial pilot-scale pyrolysis reactor system was used to produce combustible gas and biochar at 620 °C from three sources (chicken litter, swine solids, mixture of swine subsides with rye grass).

Effects of rapeseed residue on lead and cadmium availability and uptake by rice plants in heavy metal contaminated paddy soil
Yong Sik Ok,Adel R.A. Usman,Sang Soo Lee,Samy A.M. Abd El-Azeem,Bong-Su Choi,Yohey Hashimoto,Jae E. Yang +6 more
TL;DR: The incorporation of rapeseed residue into the metal contaminated rice paddy soils may sustain SOM, improve the soil chemical and biological properties, and decrease the heavy metal phytoavailability.

Effect of Natural Organic Substances on the Surface and Adsorptive Properties of Environmental Black Carbon (Char): Pseudo Pore Blockage by Model Lipid Components and Its Implications for N2-Probed Surface Properties of Natural Sorbents
TL;DR: It is concluded that benzene adsorption to char predominates at interior pore sites and does not correlate with N2-probed micropore properties when the char accrues pore-blocking substances from the surroundings, and the findings question the suitability of N2 for probing hydrophobic microporosity of BC in soils and sediments.
