The modified biochars enhanced Cr(VI) reduction by 55% (SM-BC-M) compared to manure (29%, SM) and manure-derived biochars (40% reduction, SM-BC). Among the modified biochars, SM-BC-M showed a higher Cr(VI) reduction rate (55%) than PM-BC-M (48%) in Soil 2. Various oxygen-containing surface functional groups such as phenolic, carboxyl, carbonyl, etc. on biochar surface might act as a proton donor for Cr(VI) reduction and subsequent Cr(III) adsorption. This study underpins the immense potential of modified biochar in remediation of Cr(VI) contaminated soils.]]> Thu 16 Aug 2018 13:28:48 AEST ]]> Biochar-induced concomitant decrease in ammonia volatilization and increase in nitrogen use efficiency by wheat https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:23888 −1 soil) followed by PM (124.2 mg kg−1 soil) and DAP (99 mg kg−1 soil). Ammonia volatilization was reduced by approximately 70% with PL-BC and MS-BC. The decreased NH3 volatilization with biochars is attributed to multiple mechanisms such as NH₃ adsorption/immobilization, and nitrification. Moreover, biochar increased wheat dry weight and N uptake as high as by 24.24% and 76.11%, respectively. This study unravels the immense potential of biochar in decreasing N volatilization from soils and simultaneously improving use efficiency by wheat.]]> Sat 24 Mar 2018 07:13:40 AEDT ]]> Mechanistic insights of 2,4-D sorption onto biochar: influence of feedstock materials and biochar properties https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:32949 −1) 2,4-D sorption capacity, which was attributed to the high specific surface area (576 m² g−1). The mechanism of 2,4-D removal from aqueous solution by biochar is mainly attributed to the formation of heterogeneous sorption sites due to the steam activation.]]> Fri 30 Aug 2019 13:07:53 AEST ]]> Advances and future directions of biochar characterization methods and applications https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:32017 Fri 20 Apr 2018 14:47:48 AEST ]]>
