Journal ArticleDOI
Sorption of tetracycline on biochar derived from rice straw under different temperatures.
TL;DR: Biochars produced from the pyrolysis of waste biomass under limited oxygen conditions could serve as adsorbents in environmental remediation processes and are highlighted as a promising candidate for low-cost removal of tetracycline from water.
Journal ArticleDOI
Use of Mg/Ca modified biochars to take up phosphorus from acid-extract of incinerated sewage sludge ash (ISSA) for fertilizer application
Le Fang,Jiang-Shan Li,Jiang-Shan Li,Shane Donatello,Christopher R. Cheeseman,Chi Sun Poon,Daniel C.W. Tsang +6 more
TL;DR: In this paper, the authors used Mg/Ca-modified biochars to take up P from the acid-extract from incinerated sewage sludge ash (ISSA) at low pH.
Journal ArticleDOI
Synergy effects of biochar and polyacrylamide on plants growth and soil erosion control
TL;DR: In this article, the authors evaluated the effect of biochar, PAM or their mixture (BC+PAM) on soil quality, plant growth, and runoff and soil loss under simulated and natural rainfalls.

In situ sediment treatment using activated carbon: A demonstrated sediment cleanup technology
Clayton R Patmont,Upal Ghosh,Paul LaRosa,Charles A. Menzie,Richard G. Luthy,Marc S. Greenberg,Gerard Cornelissen,Espen Eek,John Collins,John Hull,Tore Hjartland,Edward Glaza,John Bleiler,James Quadrini +13 more
TL;DR: General approaches for applying activated carbon amendments as an in situ sediment treatment remedy are reviewed, indicating that in situ sequestration and immobilization treatment of hydrophobic organic compounds using either installation approach can reduce porewater concentrations and biouptake significantly, often becoming more effective over time due to progressive mass transfer.

Adsorption/desorption behavior of cationic and anionic dyes by biochars prepared at normal and high pyrolysis temperatures
Jong-Hwan Park,Jong-Hwan Park,Jim J. Wang,Yili Meng,Zhuo Wei,Ronald D. DeLaune,Dong-Cheol Seo +6 more
TL;DR: In this paper, the authors evaluated the properties of biochar prepared at higher than normal biochar production temperature and evaluated adsorption/desorption characteristics for three commonly used dyes of different charge and molecular nature: Methylene Blue (MB), Orange G (OG) and Congo Red (CR).

Dynamic molecular structure of plant biomass-derived black carbon (biochar)
TL;DR: A molecular-level assessment of the physical organization and chemical complexity of biomass-derived chars and, specifically, that of aromatic carbon in char structures suggests the existence of four distinct categories of char consisting of a unique mixture of chemical phases and physical states.
