Abstract
Abstract
Rosmarinus officinalis was used in CVD Aided Spray Pyrolysis is to produce multi-walled carbon nanotubes (MWNTs) with a Fe-Co-Mo catalyst supported on silica using argon inert environment. The temperature at which MWNTs were formed varied from 550 to 750°C. Scanning electron microscopy (SEM), high-resolution transmission electron microscope (HRTEM), X-ray diffraction analysis, and Raman spectrum measurements were employed to characterize the as-grown MWNTs. HRTEM and Raman spectroscopy learning validated the progress of MWNTs 20–30 nm in diameter. The viability of using as-grown MWNTs as an adsorbent for removing Pb (II) ions from drinking water was studied. The Langmuir and Freundlich equations were exploited to interpret adsorption isotherm data. Kinetic data was analyzed by means of Elovich, pseudo-first-order, and pseudo-second-order equations.
