Advanced Nanocomposites for Removal of Heavy Metals from Wastewater

摘要

Water pollution is one of the major concerns around the world. Presence of inorganic pollutants such as heavy metals (i.e., Pb~(2+), Hg~(2+), Cd~(2+), As~(3+), As(V) ions, Cr(VI) ions, Co~(2+),Cu~(2+), Ag+, Ni~(2+), Zn~(2+), etc.) in water is a severe environmental and public health problem, since the accumulation of these non-biodegradable heavy metals in human body cause severe diseases. This review systematically summarizes the application of advance nanocomposites based materials for removal of heavy metals from waste water. The review covers the following topics: role of inorganic nanomaterials, polymer based nanocomposites, chitosan based nanocomposites, carbon nanotubes/metal/metal oxide nanocomposites, nanocomposites based on inorganic fillers and graphene/graphene oxide, etc. The goal of this study is to provide the latest and advance analysis as well as references in the area of developing nanotechnology.
