“…S1). The FTIR spectral properties of the rice straw biochar showed a much stronger absorption for the conjugated C]O bonds in aromatic rings (1581 and 1559 cm À1 ) (Luo et al, 2011), the CeOeC stretching vibrations in cellulose and hemicelluloses (at 1086 and 1092 cm À1 ), and the CeH stretching vibrations in adjacent aromatic hydrogen atoms (at 798 and 794 cm À1 ) (Yang et al, 2016b) than those of the bamboo biochar (Fig. S2).…”

“…Biochar is the solid product from the pyrolysis of waste biomass, such as agricultural and forestry residues, manures and dead animals (Liu et al, 2011;Ok et al, 2015;Wang et al, 2010;Yang et al, 2016b). Extensive work has been done on how biochar might mitigate global warming by sequestering C from atmosphere into soil (Dong et al, 2013;Lehmann, 2007).…”

“…It may also be used to remediate contaminated soil [10][11][12] or sequester carbon [13,14]. The processing method and pyrolysis temperature are the decisive elements affecting biochar yield, but chemical and physical properties of the feedstock cannot be ignored [15,16]. There has been considerable research regarding the use of biochar as a soil amendment, including the effect of pyrolysis conditions and substrate type on biochar quality [8].…”

Waste residues produced by agricultural and forestry industries can generate energy and are regarded as a promising source of sustainable fuels. Pyrolysis, where waste biomass is heated under low-oxygen conditions, has recently attracted attention as a means to add value to these residues. The material is carbonized and yields a solid product known as biochar. In this study, eight types of biomass were evaluated for their suitability as raw material to produce biochar. Material was pyrolyzed at either 350 • C or 500 • C and changes in ash content, volatile solids, fixed carbon, higher heating value (HHV) and yield were assessed. For pyrolysis at 350 • C, significant correlations (p < 0.01) between the biochars' ash and fixed carbon content and their HHVs were observed. Masson pine wood and Chinese fir wood biochars pyrolyzed at 350 • C and the bamboo sawdust biochar pyrolyzed at 500 • C were suitable for direct use in fuel applications, as reflected by their higher HHVs, higher energy density, greater fixed carbon and lower ash contents. Rice straw was a poor substrate as the resultant biochar contained less than 60% fixed carbon and a relatively low HHV. Of the suitable residues, carbonization via pyrolysis is a promising technology to add value to pecan shells and Miscanthus.

“…Biochar typically has a high sorption capacity for contaminants, and on a long-term basis, it may also sequester C (Zhang et al 2014; Dong et al 2015). Due to its large specific surface area (SSA), a variety of surface functional groups (hydroxyl, phenolic, carboxyl), microporous structure, high cation exchange capacity (CEC), and high pH, biochar is often regarded as an environmentally friendly and efficient sorbent for immobilizing heavy metals in aqueous environments and/or in pore water of soils and sediments (Zhang et al 2013; Yang et al 2016a, b). Many previous studies have reported high sorption capacities of biochars for different pollutants (Mohan et al 2007; Keiluweit et al 2010).…”

“…Several organic waste materials have been reported to be good feedstocks for producing biochar (Wang et al 2010; Xu et al 2013; Yang et al 2016b). These have been successfully applied for removal of heavy metals from aqueous environment (Mohan et al 2007; Xu et al 2013).…”

Biochar has received widespread attention as an eco-friendly and efficient material for immobilization of toxic heavy metals in aqueous environments. In the present study, three types of coconut fiber-derived biochars were obtained by pyrolyzing at three temperatures, i.e., 300, 500, and 700 °C. In addition, nine types of biochars were prepared by chemical modification with ammonia, hydrogen peroxide, and nitric acid, respectively, which were used to investigate changes in physico-chemical properties by inter alia, Fourier transformation infrared spectrophotometry (FTIR), scanning electron microscope (SEM), and BET specific surface area analysis. Batch sorption experiments were carried out to determine the sorption capacity of the biochars for lead (Pb) in aqueous solutions. Results showed that the cation exchange capacity of biochar pyrolyzed at 300 °C and modified with nitric acid increased threefold compared to the control. Loosely corrugated carbon surface and uneven carbon surface of the biochar pyrolyzed at 300 °C were produced during ammonia and nitric acid modifications. Removal rate of Pb by the coconut biochar pyrolyzed at 300 °C and modified with ammonia was increased from 71.8 to 99.6 % compared to the untreated biochar in aqueous solutions containing 100 mg L−1 Pb. However, chemical modification did not enhance adsorption of Pb of the biochars pyrolyzed at higher temperatures (e.g., 500 or 700 °C), indicating that resistance of biochars to chemical treatment increased with pyrolysis temperature.Electronic supplementary materialThe online version of this article (doi:10.1007/s11356-016-7428-0) contains supplementary material, which is available to authorized users.
