Chitosan is a natural amino polymer. It is eco-friendly, biocompatible, biodegradable, cost-effective, easily available and
has high potential to be utilized as an adsorbent. Because of their excellent chelating power, chitosan-based adsorbents have
a very high ability to bind pollutants present in contaminated water and wastewater. Keywords: Wastewater Treatment, Adsorbent,
