This paper presents a report on kinetics of malachite green (MG) dye removal from model aqueous solutions using a biomaterial formed by corn cob activated carbon (CCAC). The sorbent was characterized using specific surface area and pore size distribution (Brunauer–Emmett–Teller, BET) analysis. The BET analysis confirmed the macro-porosity of the adsorbent. Effects of initial concentration of MG dye and CCAC quantity, particle size and stirring rate on adsorption capacities and efficiency were monitored through pseudo first- and second-order models, intra-particle and film diffusion models to present adsorption rate parameters. The removal efficiency of MG increased with the adsorbent quantity and particle size.

Keywords: corn cob biomass, activated carbon, malachite green, aqueous phase, characterization techniques, kinetics.
