چکیده انگلیسی
MnS2, MnS2/Chitosanâsodium Alginate (MnS2/CS-NaAlg) and MnS2/Chitosan-Calcium Alginate (MnS2/CS-CaAlg) nanocomposites were prepared via the chemical procedure. The characterization was performed by various instruments such as energy dispersive X-ray spectrometer (EDX), scanning electron microscopy (SEM), X-ray diffraction (XRD) elemental map analysis, Fourier transform infrared spectrometry (FT-IR), Brunauer-Emmett-Teller (BET) surface area measurements, UV-Vis absorption spectra and X-ray absorption spectroscopy. The mean crystallite sizes of MnS2, MnS2/CS-NaAlg and MnS2/CS-CaAlg are 60.12, 71.25 and 74.54â¯nm, respectively. From Kubelka-Munk equation, the energy band gaps of MnS2, MnS2/CS-NaAlg and MnS2/CS-CaAlg are estimated to be 2.83, 2.71 and 2.41â¯eV, respectively. The investigation of photocatalysis properties was performed by degradation of tramadol under UV light illumination. The optimum of experimental variables such as pH and time on photo-degradation were found 3 and 60â¯min, respectively. The results show that the efficiency photocatalysis of MnS2/CS-NaAlg and MnS2/CS-CaAlg nanocomposites under was higher than MnS2. The antibacterial and fungicidal property of MnS2/CS-NaAlg and MnS2/CS-CaAlg nanocomposites was investigated and demonstrates good efficiency in antimicrobial efficiency compared to MnS2. The MnS2, MnS2/CS-NaAlg and MnS2/CS-CaAlg have been shown excellent mechanical and antioxidant properties.
