What Are the Key Nanomaterials Used in Water Filtration?
Several nanomaterials are commonly used in water filtration, including:
- Carbon Nanotubes (CNTs): Known for their exceptional mechanical strength and electrical conductivity, CNTs are effective in removing organic contaminants and heavy metals. - Silver Nanoparticles: These particles have potent antimicrobial properties, making them ideal for disinfecting water. - Graphene Oxide: This material offers a high surface area and excellent adsorption capacity, useful for removing pollutants such as dyes and heavy metals. - Zeolites: Nanostructured zeolites are employed for their ion-exchange capabilities and effectiveness in removing cations and anions.
