Abstract

Background: In this study, manganese dioxide-coated multiwall carbon nanotube (MnO₂/CNT) nanocomposite has been successfully synthesized. Methods: The as-produced nanocomposite was characterized by different characteristic tools, such as X-ray diffraction, SEM, and FTIR. The MnO₂/CNT nanocomposite was utilized as a fixed bed in a column system for removal of lead(II) from water. The experimental conditions were investigated and optimized. The pH range between 3 and 7 was studied; the optimum removal was found when the pH was equal to 6 and 7. The thickness of MnO₂/CNT nanocomposite compact layer was also changed to find the optimum parameter for higher removal. Result: It was observed that the slower the flow rates of the feed solution the higher the removal because of larger contact time.
