摘要: The adsorption capacity of cadmium ions by pine sawdust biomass and biochar was evaluated in batch experiments. Pine biochars were pyrolyzed at 500 °C 700 obtained the absence oxygen. higher than raw (3.47 mg/g). Biochars produced showed better efficiency (6.09 mg/g) that (4.78 Also, kinetics isotherms studied. behavior fitted Langmuir pseudo-second order kinetics. In addition, desorption experiment different solutions (neutral, acidic, alkaline) conducted. neutral alkaline environments not obvious, while an acidic environment was. biochar, °C, is a potential adsorbent for removal environments.
