Carbon nanotubes (CNTs), due to surface ring currents and high specific surface area, are often used as absorbing materials and energy storage devices. This thesis focuses on use of Fe-filled CNTs as adsorbents for simultaneous filtering of methylene blue in solution. Fe-filled CNTs are made by pyrolysis of ferrocene and core structure, as revealed by XRD, SEM and TEM, is dominated by α-Fe, along with Fe3C and Fe2O3 as minority. SQUID indicate that Fe-filled CNTs are of ferromagnetic and saturation magnetization reaches a value as high as 0.85emu. UV-Vis spectrometric data confirm reduced concentration of methylene blue by Fe-filled CNTs and the adsorption mechanism resulting from the defects of hexagonal carbon network through Raman spectrometer.
