The copolymer beads prepared by suspension polymerization were decorated with MnO 2 nanoparticles and successfully implemented for the e cient removal of toxic organic contaminants from water. Copolymer-MnO 2 nanocomposite was further analysed using XRD, SEM, and optical microscope. The SEM images showed the surface characteristics of MnO 2 nanoparticles on copolymer beads. The e ciency of the copolymer-MnO 2 nanocomposite for the removal of model pollutant methylene blue and rhodamine B is then analysed by changing the concentration of pollutant. The results obtained exhibited 18.45 mg/g for methylene blue adsorption and 3.125 mg/g for rhodamine B. The adsorption equilibrium results were tted to Langmuir adsorption isotherm for both methylene blue and rhodamine B adsorption. The desorption studies were performed for ve consecutive cycles and material was showing good regenerating capacity towards both organic pollutants. The obtained results show that copolymer-MnO 2 nanocomposite is an e cient material for the removal of organic contaminants from wastewater.
