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.

Sorption of Deisopropylatrazine on Broiler Litter Biochars
TL;DR: In this article, the sorption isotherms for deisopropylatrazine, a stable metabolite of the widely applied herbicide atrazine was obtained in acidic aqueous media (pH 5.5).
Journal ArticleDOI
Is sustainability certification for biochar the answer to environmental risks
Annette Cowie,Adriana Downie,Brendan H. George,Bhupinder Pal Singh,Lukas Van Zwieten,Deborah O'Connell +5 more
TL;DR: In this paper, the potential threats to the sustainability of biochar systems, at each stage of the biochar life cycle, were reviewed, and a sustainability framework for biochar could be adapted from existing frameworks developed for bioenergy.
Journal ArticleDOI
The fate and transport of the SiO2 nanoparticles in a granular activated carbon bed and their impact on the removal of VOCs
TL;DR: No effect of SiO(2) NPs was observed on the isotherm and the kinetic studies, this is mainly due to the fast kinetics of TCE adsorption.
Journal ArticleDOI
Carbonaceous Resin Capsule for Vapor-phase Monitoring of Volatile Monoaromatic Hydrocarbons in Soil
TL;DR: In this paper, the authors used carbonaceous resin capsules for detecting benzene, toluene, ethylbenzene, and xylene (BTEX) vapors diffusing through a soil column, and investigated sensitivity to environmental factors that influence vapor phase diffusion.
