Naturally occurring polymers have a variety of sources such as plants and animals extracted using various physicochemical or biological methods. Based on their monomeric units, biopolymers can be classified as follows: polynucleotides, polysaccharides, and polypeptides. Biopolymers are renewable and have attracted significant attention in the last decade because of their cost effectiveness, biodegradability, and biocompatibility. Among different categories of biopolymers, polysaccharides have been predominantly investigated. Owing to their poor sorption capacity, biopolymers including polysaccharides are combined with nanomaterials to not only improve their properties but also to facilitate the stability of nanocomposites. In addition to the application in medicine, cosmetic, and food industries, polysaccharide-derived polymers are commonly used for developing novel nanosorbents and catalysts to be used in water/wastewater treatment. This chapter summarizes the current status of polysaccharide-derived biopolymeric nanomaterials for water treatment. Salient features of commonly used polysaccharide-derived biopolymers such as cellulose, chitosan, gum, and starch are presented. In addition, performance of polysaccharide-derived biopolymeric nanomaterials for the removal of heavy metals, dyes, and micropollutants is discussed, and future research directions are outlined.
