abstract = {This study reports the adsorption capacity of lead Pb2+ and cadmium Cd2+ of biochar
obtained from: peanut shell (BCM), “chonta” pulp (BCH) and corn cob (BZM) calcined at 500, 600 and
700 ◦C, respectively. The optimal adsorbent dose, pH, maximum adsorption capacity and adsorption
kinetics were evaluated. The biochar with the highest Pb2+ and Cd2+ removal capacity is obtained
from the peanut shell (BCM) calcined at 565 ◦C in 45 min. The optimal experimental conditions were:
14 g L−1
(dose of sorbent) and pH between 5 and 7. The sorption experimental data were best fitted
to the Freundlich isotherm model. High removal rates were obtained: 95.96% for Pb2+ and 99.05. for
Cd2+. The BCH and BZM revealed lower efficiency of Pb2+ and Cd2+ removal than BCM biochar.
The results suggest that biochar may be useful for the removal of heavy metals (Pb2+ and Cd2+) from
drinking water.},
