The presence of heavy metals in industrial wastewater, because of their capability to aggregation has many health risks to human beings. Lead metal is placed in a category of heavy metals that has harmful effects on human health, thus it is necessary to be removed from water sources and industrial effluents. Among various methods of removing cations from wastewater, adsorption by zeolites has many advantages over conventional methods. Due to the abundance of natural zeolites and their low cost, ionic exchange by natural zeolites is a more appropriate method and even in some cases, zeolites can be recovered. In this review, the adsorption of lead ions from aqueous solutions with cilinoptilolite (Iranian natural zeolite) and modified sample of this zeolite was studied. The removal efficiency of lead was increased in treated mode.
