Preparation, characterization and adsorption capacity of bauxite-carbon nanotube composite

Iraqi bauxite clay was modified by using multiwall carbon nanotube (MWCNTs) as a modifying agent. The characterization of bauxite and bauxite/carbon nanotube was accomplished by using the Fourier transform infrared spectroscopy, scanning electron microscopy, atomic forces microscopy and X-Ray diffraction techniques. Uses the bauxite and bauxite/carbon nanotube composite for methyl green dye adsorption were achieved in a batch system. The adsorption equilibrium was attained at 60 and 45 min and adsorption efficiency reached maximum of 22 and 31% for bauxite and bauxite/carbon nanotube composite respectively, at an adsorbent dose of 0.01 g and initial dye concentration of 16 mg/L. Relying on the above shows that bauxite/carbon nanotube is a suitable adsorbent for the adsorption of methyl green dye, better than the bauxite clay. © 2019 Technoscience Publications.
