Journal ArticleDOI
Influence of Pyrolysis Conditions on Surface Characteristics and Methylene Blue Adsorption of Biochar Derived from Date Seed Biomass
TL;DR: In this article, the influence of pyrolysis temperature and heating time on the physiochemical properties of the biochar was studied and the MB removal capacity was found to be positively correlated with pyroxymethylene blue (MB) temperature and temperature.
Journal ArticleDOI
Sorption and cosorption of lead (II) and methylene blue on chemically modified biomass.
TL;DR: The equilibrium Pb adsorption contents decreased with the increasing pre-loading of MB and vice versa, suggesting the competitive rather than synergistic adsorbed of the two contaminants on the biosorbents.

A review on the thermal treatment of heavy metal hyperaccumulator: Fates of heavy metals and generation of products.
Xiaoqiang Cui,Jianwei Zhang,Xutong Wang,Minghui Pan,Qiang Lin,Kiran Yasmin Khan,Beibei Yan,Tingqiang Li,Zhenli He,Xiaoe Yang,Guanyi Chen +10 more
TL;DR: It is suggested that speciation and availability of HMs in hyperaccumulator are tunable by varying treatment techniques and reaction conditions, and this information should be useful for the selective conversion of hyper Accumulator into green and valuable products.
Journal ArticleDOI
Influence of pyrolysis temperature and bio-waste composition on biochar characteristics
Leandro Rodriguez Ortiz,Erick Torres,Daniela Zalazar,Huili Zhang,Rosa Rodriguez,Germán Mazza +5 more
TL;DR: In this paper, the influence of pyrolysis temperature and feedstock composition on biochar yield and physicochemical properties was analyzed, showing that almost all physicochemical characteristics of both almond and nut shell-based biochars depended on both the pyrolysis temperature and bio-waste composition, and an interaction of the two variables was observed in their experiments.

Effects of Biochars and Compost Mixtures and Inorganic Additives on Immobilisation of Heavy Metals in Contaminated Soils
Jasmin Karer,Anna Wawra,Franz Zehetner,Gerald Dunst,Mario Wagner,Petronela-Bianca Pavel,Markus Puschenreiter,Wolfgang Friesl-Hanl,Gerhard Soja +8 more
TL;DR: In this article, the authors tested metal extractability in a contaminated soil and metal accumulation in plants in response to the application of Poplar biochar and compost-based and inorganic soil amendments.

Pyrolysis of Wood/Biomass for Bio-oil: A Critical Review
TL;DR: A review of the recent developments in the wood pyrolysis and reports the characteristics of the resulting bio-oils, which are the main products of fast wood pyrotechnics, can be found in this paper.
Journal ArticleDOI
Biochar effects on soil biota – A review
Johannes Lehmann,Matthias C. Rillig,Janice E. Thies,Caroline A. Masiello,William C. Hockaday,David E. Crowley +5 more
TL;DR: A review of the literature reveals a significant number of early studies on biochar-type materials as soil amendments either for managing pathogens, as inoculant carriers or for manipulative experiments to sorb signaling compounds or toxins as mentioned in this paper.
Journal ArticleDOI
Some aspects of the surface chemistry of carbon blacks and other carbons
TL;DR: In this paper, a review of the surface chemistry of carbon blacks and other activated carbons is given, focusing on surface oxides with emphasis on the chemical methods used in the assessment and identification of surface functional groups.
Journal ArticleDOI
Ameliorating physical and chemical properties of highly weathered soils in the tropics with charcoal – a review
TL;DR: In this paper, the authors reviewed the available information about the physical and chemical properties of charcoal as affected by different combustion procedures, and the effects of its application in agricultural fields on nutrient retention and crop production.
Journal ArticleDOI
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.
