Progress in industrialization in particular textile industries have led to the discharge of unprecedented amount of wastewater containing synthetic dyes, which pollutes the rivers and consequently causes harm to human and other living organisms. [1] Dyes and heavy metals are removed through several methods, such as adsorption, coagulation, and chemical oxidation. Notably, adsorption emerges as a standout approach. It is highly effective, environmentally friendly, cost-efficient, and versatile in removing toxic and hazardous chemicals from wastewater. [2] This research focuses on the development of efficient and cost-effective methods for the treatment of industrial wastewater. In the presented study, a novel carboxymethyl cellulose/Cationic starch/Salep/Polyelectrolyte magnetized nanocomposite was synthesized for efficient removal of both anionic Methyl orange (MO) and cationic Methylene blue (MB) dyes from contaminated water. The process of adsorption of Methyl orange and Methylene blue dyes on the surface of magnetized nanocomposite indicates several kinds of physical interactions, involving electrostatic interaction, hydrogen bonding, and π-π interactions, this finding was proved theoretically via molecular dynamic simulations. The adsorption kinetics of dyes onto nanocomposite followed the linear form of pseudosecond-order model and their equilibrium data were fitted well to the linear Langmuir model as confirmed by the calculated values of R2 , RMSE and SD.
