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.
Journal ArticleDOI
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.

Biochar as a Soil Amendment: A Review of the Environmental Implications
TL;DR: The use of biochar as a soil additive has been proposed as a means to simultaneously mitigate anthropogenic climate change whilst improving agricultural soil fertility as mentioned in this paper, and a review of what is known about both of these claims and also about the wider environmental implications of the adoption of this process is provided.
Journal ArticleDOI
Surface speciation of Cd(II) and Pb(II) on kaolinite by XAFS spectroscopy
TL;DR: The results of this study show that the Si tetrahedral sheet limited the surface complexation of Cd and Pb on Kaolinite, elevating kaolinite's permanent negative charge properties in retaining these heavy metals at its surface.
Journal ArticleDOI
Sorption of apolar and polar organic contaminants by waste tire rubber and its chars in single- and bi-solute systems
TL;DR: The enhanced adsorption of DNB and DCP on carbonized phase is primarily attributed to nonhydrophobic interactions such as π-π electron-donor-acceptor interactions and/or H bonding, and the higher partition of DCB to polymeric phase is attributed to its high hydrophobicity.

Microbial transformation of trace elements in soils in relation to bioavailability and remediation
Nanthi Bolan,Nanthi Bolan,Girish Choppala,Girish Choppala,Anitha Kunhikrishnan,Jin Hee Park,Ravi Naidu,Ravi Naidu +7 more
TL;DR: The term “trace elements” generally includes elements that occur in natural and perturbed environments in small amounts and that, when present in sufficient bioavailable concentrations, are toxic to living organisms (Adriano 2001).
