Hazelnut husk, an agricultural waste, was used to prepare an activated carbon (HHPCAC) by chemical activation using K2CO3. HHPCAC was characterized by FT-IR spectroscopy, BET surface area determination, SEM, Boehm titration, proximate, and elemental analysis. HHPCAC has a high surface area (980.9m(2)g(-1)) and contains 2.60mmolg(-1) of total acidic functional groups. HHPCAC was used for the removal of Pb(II) from aqueous solutions by investigating a number of effective factors such as initial pH, contact time, dosage, and initial concentration. Adsorption of Pb(II) ions is highly dependent on pH of the solution, and its optimal value was found to be 5.0. Time to equilibrium was found as 20h. Kinetics of Pb(II) adsorption on HHPCAC followed pseudo-second-order model. Adsorption equilibrium data were analyzed by Langmuir and Freundlich models. Maximum adsorption capacity of HHPCAC for Pb(II) was calculated as 109.9mgg(-1) using Langmuir equation. From the findings, it could be concluded that HHPCAC is a feasible adsorbent for the removal of Pb(II) ions from aqueous solutions. |
