Abstract
This paper studies the kinetics of adsorption of lead ions from aqueous solutions under static conditions on a new nanocomposite material—graphene oxide/lignosulfonate (GO/LS). The adsorption capacity of the nanocomposite with respect to lead ions was 179 mg/g at a extraction time of 20 min. The experimental kinetic dependences were processed in the coordinates of the Elovich pseudo-first- and -second-order models, as well as the Morris and Weber diffusion models and the Boyd model. The performed calculations led to the conclusion that the pseudo-second-order model most accurately describes the adsorption of Pb2+ ions on GO/LS (R2 = 0.999). In this case, the calculated adsorption capacity was 182.52 mg/g. According to diffusion models, sorption is not limited by diffusion, but the rate of the process is limited by diffusion through the film formed on the surface of the sorbent. Thus, we can conclude that the film-diffusion mechanism of adsorption of Pb2+ ions on GO/LS with a contribution to the overall rate of the process of sorbate–sorbate interaction. The results obtained allow us to state that the GO/LS nanocomposite is a promising sorbent in the processes of removing heavy-metal ions from polluted hydrogeosystems and can be considered an effective solution for ensuring the environmental safety of the environment.
