Thermal stability of biochar and its effects on cadmium sorption capacity

F Qi, Y Yan, D Lamb, R Naidu, NS Bolan, Y Liu… - Bioresource …, 2017 - Elsevier
In this study, the thermal stability of a wood shaving biochar (WS, 650° C), a chicken litter
biochar (CL, 550° C) and an activated carbon (AC, 1100° C) were evaluated by combustion
at 375° C for 24 h to remove the labile non-carbonized organic matter. Results showed that
WS and CL biochars were not thermally stable and can lose most of the organic C during
combustion. The combusted WS and CL biochars retained considerable amounts of
negative charge and displayed higher sorption for Cd (from 5.46 to 68.9 mg/g for WS and …
