چکیده

In the present study, MS nanostructures (MS NSs), and MS/chitosan nanocomposites (MS/Chit NCs) were synthesized, M= Zn, Hg. First, [M(Tu)] complex was synthesized by a simple reflux route. In the next step, MS nanostructures were prepared by thermal decomposition of [M(Tu)] precursors at 500 ˚C for 4h. Then MS/Chit NCs were synthesized. The products were characterized by XRD, SEM, EDS, FT-IR and the effect of the surfactant was investigated. XRD confirmed formation of MS NSs and MS/Chit NCs. SEM images showed morphology of the products. Finally, the application of nanocomposites as absorbents for removing organic dyes from water was studied. Two dyes were used, including methyl orange (MO) and methylene blue (MB). The absorption spectra results indicated the suitable performance of ZnS NSs in MO removal and ZnS/Chit NCs in MB removal. Water contains organic dyes which cause a potential hazard to the environment hence these dyes need to remove from the water bodies.
