ABSTRACT In this research nanofibers of polymamide 66 containing MgO and nanofibers ofpolyamide 66 containing Al2O3 nanoparticles were electrospun in order to detoxify 2 chloroethyl ethyl sulfide 2 CEES The solutions containing 10 12 and 14 W W ofpolymer and 10 12 and 15 of each of nanoparticles in formic acid were preparedusing sonicator and the effects of sonication and particle concentration on viscosity andelectrical conductivity of fluids were investigated These solutions were electorspun toproduce nanofibers Transmission Electron Microscopy TEM was applied to measure thesize of nanoparticles and to evaluate the quality of dispersions TEM was also used tostudy the distribution and size of nanoparticles in nanofibers The effects of polymer andnanoparticle concentrations on morphology and average diameter of nanofibers werestudied using Scanning Electron Microscope SEM FTIR results showed that no chemical reactions between polymer formic acid andnanoparticles took place Detoxification of 2 CEES a mimic of mustard by each of twonanoparticles was studied using gas chromatography Afterwards the ability of nanofiberscontaining these nanoparticles was studied for detoxification of this toxic chemical Results indicated that increase in the concentration of MgO and Al2O3 nanoparticles causes an increase in viscosity and electrical conductivity of fluids Due to thecontradictory effect of viscosity and electrical conductivity by varying the concentration ofnanoparticles there was not any specific trend in the fiber diameter Our Results also showed that MgO nanoparticles could not detoxify 2 CEES but Al2O3whiskers had the ability to detoxify 89 of 2 CEES under our experimental conditions The finest nanofibers containing Al2O3 nanoparticles that was electrospun in this studycould reduce 78 of 2 CEES from the reaction medium Due to about 9 physisorption of2 CEES by nanofibers The ability of these nanofibers for detoxification of 2 CEES wascalculated about 69
