*Batch experiments were conducted to study the competitive adsorption effect of Pb2+and Ni2+ ions through synthesizing zeolite. Some influencing factors were investigated to discuss the competitive adsorption effect of mixed heavy metals. The adsorption kinetic modes for the competitive adsorption of Pb2+and Ni2+ ions were also investigated. The results showed that, the adsorption efficiency of Pb2+and Ni2+ ions was increased with the increasing of zeolite dosage, while the saturated adsorption capacity was decreased gradually. The competitive adsorption order was Pb>Ni in mixed heavy metals during the whole adsorption process. In acidic environment, the Pb2+ adsorption inhibited the adsorption of Ni2+ in mixed heavy metals. The adsorption efficiency of Pb2+and Ni2+ ions was increased continuously with the rise of temperature and the prolonging of reaction time. The adsorption efficiency of Pb2+ ions was higher than that of the Ni2+ ions in different reaction temperature. The adsorption kinetics of Pb2+ and Ni2+ ions on zeolite were matched to the pseudo-second order adsorption model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
