Efficient removal of aqueous aromatic pollutants by various techniques

Abstract

Water plays a vital role in the universe for all the living organisms, but water quality gets affected by a lot of pollutants. Due to the rapid increase in industries, the disposal of numerous aromatic pollutants into the environment leads to different unpredicted effects on human health. The removal of aromatic pollutants from water is very essential for good health. Hence, this chapter focuses on the catalytic ozonation of aqueous aromatic pollutants using graphene/carbon nanotube (CNT) and their derivative materials. The various sources of aqueous aromatic pollutants were demonstrated. Some compatible treatment methods of aromatic pollutants in water with their merits and demerits were debated. The detail account of ozonation and catalytic ozonation using different materials were examined for the removal of toxic aromatic pollutants. In addition, graphene/CNT and their properties on catalytic ozonation process for the removal of aromatic pollutants were discussed. Graphene/CNT with their supported materials towards the application of catalytic ozonation was summarized by providing the operating conditions, degradation efficiency and mineralization of their products. The versatile graphene and CNT supported materials convert the toxic aromatic pollutants into non-toxic products.
