Nowadays, the treatment of wastewater from toxic heavy metals is a long standing problem due to the industrial progress in the last years. The purpose of this study was to fabricate a novel hematite@chitosan core/organically shell nanocomposite (HCS) to remove Pb(II), Cu(II) and Cd(II) ions from industrial wastewater. The nanocomposite adsorbent was characterized by FE-SEM, TEM and FTIR resulting in formation of spherical dumb shaped particles with size range 40 to 80 nm. The effect of many operating parameters such as pH, metal ion concentration, adsorbent dosage and contact time on the removal of the toxic metal ions were investigated. The maximum removal efficacy forPb (II), Cu (II) and Cd (II)  was recorded at pH 6, 4 and 6.5, respectively. The equilibrium time was 60, 60 and 30 min, respectively while, the optimum efficiency was 94% 76% and 83% removal efficiencies for Pb (II), Cu (II) and Cd (II), respectively at initial concentration 10 mg/l.  The adsorption isotherms were better matched by the Langmuir model and the metal ions adsorption capacity were 129.8, 63.2 and 69.9 mg/g, for Pb (II), Cu (II) and Cd (II), respectively. Successive adsorption-desorption cycles occur by the adsorbent confirmed that HCS NC can be reused after recovery of ionsby disodium salt of EDTA solution without significant capacityloss.
