Abstract

Volatile Organic Compounds (VOCs) play a critical role in the atmosphere and are produced from biogenic and anthropogenic sources. These chemicals have serious health consequences for humans. Among many types of industrial waste available, Coal Fly Ash (CFA) are mostly produced by coal- fired power plants with the ability to capture VOCs from the air. The use of an inexpensive, high-performance electrospun nanofiber membrane to filter out airborne impurities. Adsorption is thought to be the best approach out of all of them due to its convenience, ease of usage, and easy-to-understand design. This review article covers the procedure, and environmental effects of employing fly ash for the adsorption of VOCs. The main concerns with fly ash disposal are the need for massive land areas for landfills and the harmful effects and groundwater pollution caused by the accumulation of heavy metals. Additionally, the methods for overcoming the benefits of using fly ash are also examined.
