Application of polysaccharide-based hydrogelsFor water treatments

Due to industrial development, great volumes of pollutants are generated and discharged into the environment, leading to serious problems. Among the contaminants, heavy metals and dyes are the most common and the most hazardous, as their ingestion can have a very long-lasting influence on the human organism. Various kinds of synthetic dyestuffs or heavy metals are seen in the effluents of wastewater. Dyes are colored-aromatic organic compounds and are generally classified into three groups: cationic or basic dyes, nonionic or disperse dyes, and anionic or acidic dyes. Cationic and anionic dyes are the most commonly used dyes in the textile industry due to their good solubility in water, easy application, and inexpensive characteristics.
