What Types of Nanomaterials Are Used in Groundwater Purification?
Several types of nanomaterials are employed in groundwater purification, each with specific properties suited for different contaminants. Some of the commonly used nanomaterials include:
1. Carbon Nanotubes (CNTs): Known for their excellent adsorption capabilities. 2. Metal Oxide Nanoparticles: Such as titanium dioxide (TiO2) and zinc oxide (ZnO) which are effective in photodegradation of organic pollutants. 3. Nanoscale Zero-Valent Iron (nZVI): Effective for the reduction and removal of heavy metals and chlorinated compounds. 4. Silver Nanoparticles: Known for their antimicrobial properties.
