Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Science - Department of Physical Chemistry Summary: Hydroxyapatite nanorods (nHAp) and a hydroxyapatite/chitosan nanocomposite (nHApCs) were synthesized by sol gel method to participate as sorbents for the removal of some heavy metals from wastewater. The influence of different parameters on the structure quality of the produced sorbent has been investigated. Several techniques, including the high resolution transmission electron microscopy (HR-TEM), energy dispersive X-ray spectrometry (EDX), X-ray diffraction spectrophotometer (XRD), Fourier transform infrared (FTIR) spectrophotometer and zeta potential measurements, have been employed to evaluate the sorbent{u2019}s characterization. The potential of these synthesized sorbents to remove lead, cadmium, nickel, copper and zinc ions from aqueous solutions was investigated in batch experiments, where several parameters such as the sorbate/sorbent's contact time, initial metal ions concentration, pH and sorbent dosage were investigated. The equilibrium concentration of metal ions were identified by the atomic absorption spectrophotometry
