Abstract

Groundwater is frequently utilised as the source of consuming water throughout the entire globe. Hence, the defilement of this groundwater by noxious radioactive metals like Uranium (VI) which are produced from the expansion in thermal energy stations, radio-nuclear plants as well as their releasing by-product materials, which are delivered into the conduits and waterways is a pressing issue.  The noxious as well as deadly Uranium (VI) is viewed as a toxic by-product related to the course of enrichment process used to create atomic energy, and also the risk factor associated with it is caused by the radioactivity, carcinogenicity and toxicity of uranium. Numerous strategies have been proposed to manage these issues, yet photocatalytic degradation stands apart as a simple, cost-effective, and efficient process that has acquired huge consideration as of late in spite of specific constraints concerning its functional and operational applications. The various photocatalytic reagents and their applications for removing uranium (VI) from radioactive wastewater are summed up in this review.
