Carbon Nanotube (CNT) Adsorbent for Water Purification¶
Coagulation & Advanced Treatment • Est. CapEx: $500 USD • Lifespan: 7–15 Years
Technical Overview¶
Carbon nanotube-based adsorbents are engineered nanomaterials applied to water purification, capable of removing organic and inorganic pollutants from wastewater and irrigation water. Leveraging extremely high specific surface area and tunable surface chemistry, CNT adsorbents represent a promising nanotechnology solution for capturing heavy metals and hazardous contaminants.

| Primary Mechanism | Contaminants adhere to the outer and inner surfaces of multi-walled or single-walled carbon nanotubes through physisorption (van der Waals forces) and chemisorption (surface functional groups). The high aspect ratio and large specific surface area of CNTs provide abundant binding sites for metal ions, organic compounds, and other pollutants, enabling efficient removal even at low concentrations. |
