Nano-composites based on Chitin for the Removal of Heavy Metals from Wastewater: A Mini Review

Published: April 28, 2025

Water pollution, mostly due to industrial discharge, is considered be one of the significant challenges globally. There are various industries like leather tanning, electroplating, textile and dyeing units which heavily contribute pollution aquatic system by heavy metals. These metals being non-biodegradable toxic assemble in living beings, leading severe health issues damage environment. Among water treatment mechanisms, adsorption as most effective ways treat waste water, offering advantages such simple design, non-toxicity, cost effectiveness, better efficiency discarding pollutants spite very low concentrations. In thepast, natural polymer based composites for process has gained popularity. this context, chitin-based nanocomposites have shown great potential on account their renewable, biocompatible, eco-friendly traits, making them ideal candidate elimination Chitin, owing its built-in antibacterial properties, functional versatility biodegradability, utilized fabricate that effectively bind metal ions remove it from wastewater. The unique structure chitin, with numerous groups, provides chelation sites facilitate excellent binding ions. This review highlights extraction, properties modification chitin. Further deals development chitinbased adsorbents eradication out contaminated water.
