Study on surface adsorption of sulfur chemicals agents simulants using polyacrylonitrile and polyoxomolybdate nanofibers

In the present study, composite nanofibers PAN NFs/[Mo132] was prepared using polyacrylonitrile and supramolecular nanostructure [Mo132] under electrospinning process. The aim of this study was to investigate the adsorption of blister-like chemical agents such as 2-chloroethyl ethyl sulfide and 2-chloroethyl phenyl sulfide in the presence of these nanofibers. The structure of nanofibers, surface morphology, and other properties were characterized by SEM, TEM, FT-IR and UV-Vis methods. The average diameter of nanofibers using SEM images was about  80 nm. PAN/[Mo132] nanofibers showed an adsorption efficiency of about 92-94% after about 4 hours. The progress of the reaction was examined by gas chromatography. The results showed that the rate and amount of the adsorption of 2-CEES and 2-CEPS increased with increasing the amount of [Mo132], which indicates the effect and role of this nanocluster in the performance of nanofibers. In this study, the effect of factors such as amount PAN/[Mo132], time, temperature and solvent on the rate of adsorption process was investigated.
