The aim of this study was to find out an available and low cost material to reach the permissible levels of the heavy metals Mn²⁺ , Fe²⁺ and pb²⁺) in the contaminated water (ground and industrial waste water) taken from Kaha, El-Qulayoubia Governorate using multi walled carbon nanotubes ( MWCNTs) prepared from chemical vapor deposition      (CVD) and ferric oxide nanoparticle(Fe₂O₃) with potassium permanganate(KMnO₄). Also, it involved the characterization of MWCNTs and  Fe₂O₃ nanoparticle and determine the optimal conditions for the treatment. The effects of MWCNTs,  Fe₂O₃ nanoparticle and KMnO₄ on removal of manganese , iron  and lead from contaminated water was the main target of this investigation. In this work the highest initial Mn²⁺ , Fe²⁺ and pb²⁺ ion concentrations (C₀) were found to be 3.42 , 4.2 and 23 mg/L, respectively, were treated with multiwall carbon nanotubes ,ferric oxide and potassium permanganate. MWCNTs was of  20-30 nm outer diameter, 5-10 nm internal diameter, surface area of 207.13 m²/g, carbon content 90.05%, oxygen content 6.9% and purity above 87%,while, Ferric oxide particle size averaged     5-10 nm, ferric content 44.64%, oxygen content 41.67% and carbon content 10.97%. The optimum conditions for removing Mn²⁺ and Fe²⁺ ion from the contaminated water with MWCNTs/KMnO₄, were a pH of 7.5, volume KMnO₄ 0.25 mL, adsorbent weight  of 0.05 g and a contact time of  90 min. The optimum conditions for removing Pb²⁺ ion with Fe₂O₃/KMnO₄ were a pH at 6.7, adsorbent weight 0.06 g, volume of KMnO4 1.25 mL and a contact time of 120 min.
