Abstract:

One of the most significant challenges facing environmentalists today is maintaining the cleanliness of waste water. Many different types of heavy metal ions are produced by industries and then discarded in water. Carbon Nano Tube (CNT) has the potential to decontaminate waste water by removing this contaminant via the process of adsorption. CNTs have a huge surface area, a light mass density, a highly porous and hollow structure, and a strong interaction between the pollutant molecules and themselves. In addition, acid-modified and functional group-grafted CNTs have a higher level of activity when it comes to the removal of heavy metal ions. By means of photocatalytic degradation, CNT is capable of removing both organic and metal pollutants. CNT has the capacity to regulate and adsorb granular and bulky particles, as well as bacteria and the salt impact in water. CNT has the ability to remediate waste water that is infested with germs because to its antibacterial action. Because of the photocatalytic activity of CNT, it is possible to cure water that has been polluted with dye. CNTs adsorption efficacy is impacted by a wide variety of factors, including but not limited to pH, temperature, and contact duration, ionic strength of metal ions, CNTs dosage, and surface charge. As CNTs are cost effective, in this study we will review on the application of CNTs in the treatment of water.
