This study investigates novel multi-walled carbon nanotubes (MWCNTs) grown on agricultural waste, using loaded iron nanoparticles as catalyst templates and acetylene as carbon source through chemical vapor deposition under specific conditions, to wit: 550 degrees C reaction temperature, 47 min reaction time, and 1 gas ratio. The specifications of MWCNTs are analyzed and characterized with the use of field-emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, transmission electron microscopy, Fourier-transform infrared spectroscopy, X-ray diffraction, ther- mogravimetric analysis, Brunauer-Emmett-Teller surface area analysis, and zeta potential analysis. The results reveal that MWCNTs have high quality and unique morphologies. The removal and capacity of Al are optimized through response surface methodology, whilst the adsorption kinetics results are well ascribed to the pseudo-second-order model, the isotherm data are effectively fitted using a Langmuir model. The maximum adsorption capacity is 393.52 mg/g. The results demonstrate that MWCNTs can be regarded as a new low-cost adsorbent in wastewater treatment for the removal of Al-3(+).
