ABSTRACT
Effective and efficient removal of contaminants is a significant challenge in wastewater treatment. Among various available techniques, adsorption is an economical, efficient, and simple process for the removal of contaminants from the wastewater. Ideal adsorbent for the wastewater treatment should have characteristics like economical, easy availability, renewability, and opportunity to modify the surface of adsorbent to remove a wide range of contaminants from the wastewater. Recently, there is a significant research interest on adsorbents derived from natural material. Polysaccharide is one of most abundant carbohydrate polymeric materials composed of monosaccharide unit attached together by glycosidic linkages. A wide range of polysaccharides are available in nature, which can be used to effectively remove various contaminants from the wastewater. This chapter presents a review and overview of various polysaccharide-based adsorbents for the wastewater treatment. This chapter mainly focused on chitin, chitosan, starch, and cyclodextrin-based adsorbents for the wastewater treatment.
