Application of Chitosan Nanoparticles in the Adsorption of Heavy Metals from Wastewater: A Concise Review

Abstract

The biopolymer chitosan is a biodegradable, biocompatible polymer that has been scientifically proven to be an efficient organic compound for the adsorption of heavy metals from a variety of industrial wastewater. Heavy metals are toxic and can cause a variety of harmful health effects, even in low concentrations. Therefore, it is important to remove them from the wastewater to ensure the water is safe for consumption and other uses. Chitosan is a superior adsorbent because it contains functional groups like hydroxyl and amino. Nano-chitosan can be fabricated using various methods but modern nanotechnology research focuses on developing highly efficient and cost-effective green technology. The remarkable physicochemical features of nano-chitosan make it suited for usage in enhancing the durability and washability of textile supplies as well as giving them antibacterial capabilities.
