A high CEC value indicates that not only can the biochar sample be used as a carbon
sequestration agent, but also as a valuable soil amendment for increasing a soil’s natural CEC. Biochar
was characterized using elemental analysis, SEM, BET surface area, FTIR, and XRF. These results showed
that biochar produced via slow pyrolysis possesses several highly beneficial attributes. The metal
adsorption characteristics of biochar were studied in presence of various controlling parameters such as
pH, contact time, adsorbent dosage, and interfering species
