The present study examines the removal of Cd2+ from mono-metal aqueous solution using pine-fruit residue (PFR) biochar adsorbent. The influence of varying pH, Cd2+ concentration and contact time at 303 K was examined for adsorptive removal of Cd2+ in batch mode. The equilibrium data were analyzed by modeling of Freundlich and Langmuir isotherm using both linear and non-linear regression methods. Langmuir model represented the best fit to the Cd2+ adsorption on biochar and the isotherm parameters were better predicted by non-linear regression. The kinetic data for Cd2+ adsorption followed pseudosecond order model.
