In this study, a green process for the synthesis of Mn and Cu oxides in chitosan membranes is reported. The process consists of two steps: (1) synthesis of Mn/Mn2O3 nano/microstructures in the presence of onion via hydrothermal method, (2) synthesis of Mn/Cu/O/chitosan nanocomposites using chitosan, CuO powder, and Mn/Mn2O3 prepared in the first step. The SEM images showed formation of the bundles of spherical Mn/Cu/O/chitosan nanocomposites. The XRD patterns confirmed the formation of the nanocomposites. The problem of water pollution is of a great concern and adsorption is one of the most efficient techniques for removing the pollution from the solvent phase. The nanocomposites synthesized in this work can help us to solve the waste disposal problem. They are effective adsorbents for MB and phenol removal from aqueous solution. In UV-Vis spectra, the intensity of peaks of MB and phenol are decreased after their adsorption on the surface of the nanocomposite.
