The adsorption equilibrium studies were carried out as a function of contact time, adsorbent dosage, pH, temperature, and initial Pb2+ concentration. The results showed that the equilibrium time of adsorption was achieved within 60 min, and the effective pH was selected to be 5 (natural pH). The maximum adsorption capacity of Pb2+ on n-Hap was found as 565 mg.g-1. It is believed that the results obtained for adsorption may provide a background for the detailed mechanism investigations and the pilot and industrial scale applications.}, journal = {International Journal of Chemical and Molecular Engineering}, volume = {10}, number = {8}, year = {2016}, pages = {1017 - 1020}, ee = {https://publications.waset.org/pdf/10005112}, url = {https://publications.waset.org/vol/116}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 116, 2016}, }
