This study reports the synthesis of metal sulfide/chitosan nanocomposites (MS/chit NCs), M=Ni, Cd, via three steps: (1) synthesis of M(Tu) complex, Tu=thiourea, by a simple reflux route, employing metal nitrates and thiourea as the reactants (2) synthesis of MS nanostructures by simple thermal decomposition method using [M(Tu)] as precursors (3) synthesis of MS/chitosan nanocomposites. The fabricated nanostructures and nanocomposites were characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). The adsorption is one of the most efficient techniques for removing the pollution from the solvent phase. The nanocomposites synthesized in this work could help to solve the waste disposal problem. They were applied for the MB removal from aqueous solution. The intensity of peaks of MB were decreased after their adsorption on the surface of the nanocomposites in UV-Vis spectra. https://jns.kashanu.ac.ir/article_114427_3f99298412da8d08aee1cca2bda7b462.pdf
