“…These shifts are quite typical for complexation of metal ions by coordination with carboxylic groups. Peaks observed at 470, 780-880, and 1 000-1 100 cm −1 were ascribed to the bending vibration, symmetric stretching vibration, and asymmetric vibration of the Si-O-Si bond, respectively (Cui et al 2016). Other shifts occurred at 1 103 and 784 cm -1 after sorption of Pb and Cd by MBC, respectively, suggesting the involvement of Si-O-Si bonds in metal adsorption.…”

“…As compared to the wheat straw treatment (non‐pyrolyzed material), addition of wheat straw‐biochar at 8 and 16 t ha −1 significantly increased the total SOC sequestration rate in the soil depth of 0–100 cm by 35.6% and 28.1%, respectively. In a 5‐year experiment under heavy metals contaminated paddy field, Cui et al () reported that the soil SOM content under wheat straw‐biochar treatment was significantly enhanced by 8.9–44.2% in 2010, 9.4–42.3% in 2011, 23.1–59.3% in 2012, 9.8–37.8% in 2013 for wheat season and 10.0–57.0% in 2010, 16.1–50.9% in 2011, 16.1–50.9% in 2012, and 8.1–31.4% in 2013 for rice season compared to control treatment. Arthur, Tuller, Moldrup, and de Jonge () investigated the potential effects of birch wood‐biochar (BW‐BC) aging on the SOC for 19 months and 07 months under field conditions.…”

“…As compared to the wheat straw treatment (non-pyrolyzed material), addition of wheat straw-biochar at 8 and 16 t ha −1 significantly increased the total SOC sequestration rate in the soil depth of 0-100 cm by 35.6% and 28.1%, respectively. In a 5-year experiment under heavy metals contaminated paddy field, Cui et al (2016) (2014) Biochar is a highly stable material owing to its recalcitrant aromatic structure, with less than 1% of fresh biochar degraded in soils following application (Kuzyakov, Subbotina, Chen, Bogomolova, & Xu, 2009). The mineralization rate of biochar depends on the mineralizable C content in biochar, the quantity of which varies with the type of feedstock and temperature of pyrolysis (Singh, Cowie, & Smernik, 2012).…”

“…The FTIR results revealed that the different BCs had different functional groups, which could be attributed to the biochar species (Xiao et al 2016). The biochar properties considerably affect the interactions between 2,4-DCP and the functional groups during the sorption process (Cui et al 2016). Fang et al (2015) found that the persistent free radicals (-OH) could be activated on carbonaceous materials, such as biochar, and that the oxygenated functional groups were key factors in the formation of persistent free radicals.…”

“…Biochar prepared from agricultural wastes through pyrolysis is a potentially attractive adsorbent for the organic pollution control because of its high sorptivity, rich carbon source, small ecological risk, and minimal secondary contamination (Lehmann et al 2011;Lou et al 2011). The BC contains various functional groups and microcellular structures, which enhances its efficiency to remove and remediate various organic and inorganic pollutants (Lou et al 2012;Cui et al 2016). Many studies have reported that biochar is an efficient adsorbent for the remediation of various organic pollutants, such as phenol , 4-chlorophenol (Shih et al 2012), and polycyclic aromatic hydrocarbons (Oleszczuk et al 2012).…”
