Abstract

Water pollution has produced a significant threat to the ecological system as well as public health.The higher level of pollutants in wastewater bodies can reach to humans and can cause serious neurotoxicity, blood toxicity, kidney ailments, liver damage, and teratogenicity. The discharge of different pollutants generated from fertilizers, pesticides, leached from landfill, textile, leather, paper production, industries is a great threat to the ecosystem. A varied range of conventional treatment methods and techniques (e.g. chemical coagulation, activated sludge, trickling filter, carbon adsorption, and photodegradation techniques) for removal such pollutants have been used and investigated extensively. But the real problem remains a huge threat as these pollutants are not been actually removed but transformed from one media to other. Thus, a novel approach with a goal of complete destruction of these pollutants is a need of time. The nano-size catalysts can provide a sustainable approach and curb the problem to a greater extent. The metal coordinated nanocatalyst with organic framework can add new avenues for this research so that smaller amounts of well-coordinated metal catalysts can destroy larger amounts of pollutants with least possibility of leaching the coordinated metals as the organic framework can provide a large number of functional groups.
