Removal of Pb2+ Ions from Aqueous Solution Using Posdonia Oceanica Collected From Tajora Beach (Libya)
Abstract
The seagrass posdonia oceanic (P.O) was collected from Tajora Beach and employed to remove Pb ions from aqueous solutions. The P.O samples were dried, ground and characterized by SEM, POM and FTIR analysis. The batch mode study showed the removal percentage of Pb2+ icreases up to 88.1 % at 6 hrs using P.O. The maximum capacity of lead removal was found to be 28.82 mg/g. The adsorbed amounts of Pb2+ have decreased from 3.71 to 0.22 mg/g as pH increased from 4 to 10. The removals of Pb have positive relationship with temperature and the mass of P.O. The activation energy of Pb2+ removal is + 4.1 kJ/mole which suggests the endothermic nature of reaction.
