摘要

The use of pine bark, a natural adsorbent prepared from Korean Red Pine (Pinus densiflora), was studied for its sorption behavior of lead ion from aqueous solution. Adsorption experiments were carried out on lead ion concentrations of 10 mg/l. Adsorption of lead ion could be described by both Langmuir and Freundlich adsorption isotherms. Treatment of the bark with nitric acid greatly increased initial sorption rate, and equilibrium sorption capacity increased by about 48%. A pseudo second-order kinetic model fitted well for the kinetic behavior of lead ion adsorption onto the bark. Acid-treated bark demonstrated its sorption capacity quite close to that of granular activated carbon. Results of this study indicated that ion exchange and chelation were involved in the sorption process.
