| Abstract: |
| Selenium is a necessary element in human body and wound healing. Since selenium nanoparticles (SeNPs) show a much lower risk compared to selenium, it has found a widespread use as an antioxidant and a dietary supplement. In this study, a facile in situ sonosynthesis method is introduced for synthesis and loading of SeNPs on cotton fabric by using sodium selenite and ascorbic acid in a sonobath. The amount of salt, acid and processing time were selected as three variables that optimized with Design of experiments (DOE). The red color of the product was attributed to the formation of SeNPs. The percentage of hydrogen peroxide scavenging of the treated fabric samples was found through UV-Vis absorbance. The structure, size, morphology of SeNPs were characterized by field emission scanning electron microscopy (FESEM), UV-VIS, FTIR and EDAX. The UV-Vis spectrum of the remaining solution indicated the maximum absorption at 266 nm confirming the presence of SeNPs in the solution. All the diffraction peaks in the XRD pattern and FESEM images confirmed the size of SeNPs in the nano range. The current study suggested that SeNPs can be used as a sensor for hydrogen peroxide and the processing condition possibly influence on the size and shape of SeNPs on the fabric. |
