<br/><br/> Activated carbon (AC) from sugarcane bagasse waste material and activated carbon-nano metal oxides composite (nanocomposite) were prepared and investigated by surface area analyser, X-ray diffraction, Fourier-transforminfrared spectroscopy (FT-IR) and Raman spectroscopy.The synthesized AC and the nanocomposite were utilized as adsorbents for removal of crystal violet basic dye (CV) from wastewater. To investigate the adsorption of CV by synthesized AC and the nanocomposite, batch adsorption process was conducted with varying different parameters as pH, contact time, and the dose of adsorbents. The equilibrium isotherm was examined by Langmuir and Freundlich models. Moreover, the adsorption kinetic was explored using pseudo-first-order and pseudo-second-order models
