Abstract
Heavy metals polluted soils are a significant worldwide environmental problem. The crops cultivated in polluted soils often contain significant levels of heavy metals (Cd, Pb,.. etc) that can impair human health. The current technologies such as; removing up of pollutants; stabilization/solidification of pollutants, vitrification, soil capping.., etc; used in remediation of polluted soils are not adequate. Smarter and cheaper techniques still to be addressed to decontaminate polluted soil. Nanotechnology offers a number of emerging techniques much more effective that could work to immobilize contaminants. In the present study, nanoparticles; nano scale zero valent iron 2nZVI3, nZVI - bentonite, nano alginite, nano carbon and dendrimers; are used as a potential sorbents to immobile Cd and Pb in polluted soil. These nanoparticles (except nano carbon) are prepared in lab either using top-down or bottom-up methods, then characterized using transmission electron microscop (TEM)
