The potential of adsorptive removal of Cr(VI) (hazardous element) and Au(III) (valuable element), from aqueous solutions, with carbon nanotubes was investigated. Kinetic experiments were performed in order to investigate the influence of different variables on the adsorption kinetics, that is, the stirring speed (250–2,000 min) and adsorbent dosage (0.25–1.5 g L) in the case of chromium(VI) as well as temperature (20°C–60°C) and HCl (0.1–10 M) concentration in the case of gold(III).
