Abstract: While a large-scale soil amendment of biochars continues to receive interest for enhancing crop yields and to remediate contaminated sites, systematic study is lacking in how biochar properties translate into purported functions such as heavy metal sequestration. In this study, cottonseed hulls were pyrolyzed at five temperatures (200, 350, 500, 650, and 800 °C) and characterized for the yield, moisture, ash, volatile matter, and fixed carbon contents, elemental composition (CHNSO), BET surface area, pH, pHpzc… Show more

“…Pyridine (pyridine ring vibration and C-H deformation) [53] This result is likely due to the degradation and depolymerization of cellulose, hemicelluloses and lignin [29]. Instead, intensities of O-H (1325 cm −1 ) stretching [29] and aromatic C=C and C=O stretching of conjugated ketones and quinones (1600 cm −1 ) [52] decreased with temperature which may suggest that phenolic and carboxylic compounds in lignin had been degraded [54]. There was also pyridine in biochars (781 cm −1 ) [53], which was one of the heterocyclic nitrogen compounds commonly observed during pyrolysis [55].…”

“…Biochars can also have metal sorption properties when used as a soil amendment [11,73,74]. Their ability to bind metals arises from their porosity, surface area, and surface functional groups [75,76].…”

“…Feedstock property and pyrolysis condition were described in detail in previous reports (Uchimiya et al, 2011(Uchimiya et al, , 2013aKlasson et al, 2014). Briefly, lignin (L25) was obtained from a cellulosic ethanol plant (Örnsköldsvik, Sweden) as wet powder and was air dried (Klasson et al, 2014).…”
