Many wastewater purification methods, especially adsorption, are conducted to reduce water pollution. Polysaccharide hydrogels are potential adsorbents with unique properties, such as biodegradability, hydrophilicity, high swelling ratio, and tunable surface characteristics. Through various interactions between a polysaccharide hydrogel and a pollutant, high adsorption capacity is achieved at optimum experimental conditions. Using adsorption isotherm models and kinetic models as well as thermodynamic studies, adsorption processes are investigated in detail. In the case of good regeneration of polysaccharide hydrogels, their long-term reusability is observed. In this chapter, utilization of polysaccharide hydrogels as adsorbents for the removal of different pollutants such as dyes, heavy metals, and pharmaceuticals is stated. The maximum adsorption capacity of polysaccharide hydrogels is listed based on literature studies. The regeneration of polysaccharide hydrogels is mentioned by evaluating desorption parameters. © 2024 Elsevier Inc.
