| Abstract | A study on the removal of Cd (II) ions from aqueous solutions by Castanea sativa shell was conducted in batch conditions. The influence of different parameters such as adsorption time, temperature and initial concentration of Cd ions on cadmium uptake was evaluated. Results indicated that cadmium adsorption could be described by the Freundlich adsorption model in the studied concentration range of cadmium (II) ions at all the temperatures essayed, predicting the heterogeneity of the shell. The kinetics of the adsorption process followed the pseudo-second order model, with cadmium sorption capacity decreasing slightly with increasing temperature at 15.3 mg/L. Equilibrium sorption capacity increased with increasing the initial cadmium concentration. Using the second-order kinetic constants, which decreased with decreasing temperature, the energy of adsorption was calculated as equal to 19.2 kJ/mol. |
