Abstract

In this work, Multiwall carbon nanotubes (MWCNTs) were used in the adsorptive removal of Bismarck Brown R (BBR) dye from an aqueous solution. The effects of contact time, MWCNT dosage, dye concentration, pH and temperature on adsorption of BBR 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 three common adsorption models: Langmuir, Freundlich and Temkin. Gibbs free energy change values showed that the adsorptions of BBR dye on MWCNTs is spontaneous. The results also indicate that the adsorption is physisorption.
