A Kinetic Study for Removal of Bismarck Brown G by Adsorption over Multiwall Carbon Nanotubes


In this work, Multiwall carbon nanotubes (MWCNTs) were used in the adaptive removal of Bismarck Brown G (BBG) dye from an aqueous solution. Crystal structure of the materials was investigated using X-rays diffraction XRD, specific surface area (BET) and UV–Vis diffuse reflectance. The effects of contact time, MWCNT dosage, pH and temperature on adsorption of BBG dye by MWCNTs were investigated. The adsorption study was analyzed kinetically, and the results revealed that the adsorption followed pseudo-second order kinetics with good correlation coefficients. The equilibrium adsorption data was analyzed using two common adsorption models: Langmuir and Freundlich.
