Abstract
Natural superabsorbent polymers (SAP) based on cellulose and its derivatives are considered as the most abundant organic compounds which are derived from biomass. Biopolymer based superabsorbent including the polysaccharides based are economical and ecofriendly approach to many fields such as drug delivery, textiles, agricultural field, wastewater treatment, cosmetics etc. Polysaccharides especially cellulose, chitin and chitosan are important biopolymers because of their high abundance, renewability, wide distribution, biodegradability and low cost of production. The crosslinking and grafting of polysaccharides to produce hydrogels has several advantages as superabsorbent. Metal-based nanoparticles (NPs) have been used by the scientists in the fields of applied and fundamental research. Recently, polysaccharides are gaining importance as self-capping agents for synthesis of Ag NP. The paper provides a thorough review on recent developments on utilization of natural polysaccharide-based nanocomposite for various sorption applications. Specifically, their application and efficiency in organic drug delivery, antibacterial, dye removal, heavy metals removal, etc.
