英文摘要 | Basaltic rocks obtained from Qusier area, south Eastern Desert, Egypt showed to be effective in removing heavy metals from aqueous solution. According to mechanical and engineering scheme, the basaltic rocks were classified into basalt weathering grade I (BWGI) and basalt weathering grade II (BWGII). The adsorption of Pb2+ using BWGI and BWGII from aqueous solution was studied under various conditions. The uptake of Pb2+ was rapid with maximum adsorption within 90min for BWGI and 60min for BWGII. The kinetic of the Pb2+ adsorption was studied using pseudo-first-order, pseudo-second-order, Elovich and intraparticle diffusion models. The kinetics data showed that the adsorption of Pb2+ onto basalt proceeds according to the pseudo-second-order model. The results obtained from adsorption isotherm indicated that the maximum adsorption capacities of Pb2+ were 15.92 and 23.31mg/g by BWGI and BWGII, respectively. The mean sorption energy (E) obtained from Dubinin-Radushkevich isotherm model indicated that, the adsorption process takes place chemically and the reaction is endothermic. The results suggested that natural basalt, especially, BWGII is suitable as an adsorbent material for adsorption of Pb2+ from aqueous solutions. |
