Abstract
Emerging pollutants, corrosive chemicals and dyes released from the industries, harshly contaminates the landfills, environment and water reservoirs. Mass mortalities of aquatic animals in water bodies and species depletion is linked with improper release of wastewater. Pollutants released in water bodies are a threatening alarm to the human society and environment. To remove the pollutants from municipal wastewater, several techniques including adsorption, chelation, precipitation and ion exchange were employed. However, chitosan based hybrid materials (nanocomposite, hydrogel, membrane, film, sponge, nanoparticle, microsphere and flake) could serve as novel alternate materials to replace the chemical based adsorbents. The advantages of using chitosan based hybrid materials in wastewater treatment was summarized herein. Furthermore, this review aims to highlight the role of chitosan based hybrid materials for removing various pollutants and dyes from municipal wastewater.
