What are Nanomaterials used in water purification?
Several nanomaterials are used in water purification technologies, including:
Carbon Nanotubes (CNTs): Known for their high surface area and excellent adsorption properties, CNTs can remove organic pollutants and heavy metals. Graphene Oxide: This material is highly effective in removing contaminants due to its large surface area and functional groups that can bind with pollutants. Nanoparticles: Metal oxides like titanium dioxide (TiO2) and zinc oxide (ZnO) exhibit photocatalytic properties, breaking down organic pollutants when exposed to light. Nanofibers: These fibers, made from polymers like polyacrylonitrile, can be used to create filtration membranes with high efficiency. Nanocomposites: Combining different nanomaterials, nanocomposites offer synergistic effects for enhanced purification performance.
