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.

Journal ArticleDOI
Characteristics and mechanisms of hexavalent chromium removal by biochar from sugar beet tailing.
TL;DR: Results indicated that the electrostatic attraction of Cr(VI) to positively charged biochar surface, reduction of Cr-VI to Cr(III) ion, and complexation between Cr( III) ion and SBT's function groups were probably responsible for Cr( VI) removal by SBT biochar.
Journal ArticleDOI
Efficiency of green waste compost and biochar soil amendments for reducing lead and copper mobility and uptake to ryegrass.
TL;DR: Green waste compost and biochar amendments were assessed for their assistance in regulating the mobility of copper (Cu) and lead (Pb) and the resultant uptake of these metals into vegetation and harvestable amounts of Pb were reduced.
Journal ArticleDOI
Modeling and evaluation of chromium remediation from water using low cost bio-char, a green adsorbent.
TL;DR: It is remarkable that oak chars can remove similar amounts of Cr(VI) as activated carbon (S(BET): ∼ 1000 m(2)g(-1)).
Journal ArticleDOI
Catechol and Humic Acid Sorption onto a Range of Laboratory-Produced Black Carbons (Biochars)
TL;DR: It is suggested that addition of BC to soil, via natural fires or biochar amendments, will sequester abundant native OM through sorption, and greater sorption of both catechol and HA occurred on biochars with nanopores, i.e.Biochars made at higher temperatures.

Characterization and application of chars produced from pinewood pyrolysis and hydrothermal treatment
TL;DR: Two types of pinewood chars, hydrothermal char (H300) and pyrolytic char (P700) from biomass-to-energy conversion were characterized and used as adsorbent for the copper removal from aqueous solution as discussed by the authors.
