In this study, polyethylene terephthalate (PET) and different weight percentages of zeolite-8 imidazolate framework (ZIF-8) were used to investigate the performance of PET/ZIF-8 polymer media produced by solution electrospinning in removing particles from air flow compared to the HEPA filter.</span></span><br> <span style="font-size:9pt"><span minion="" pro="" style="font-family:"><b>Materials & Methods</b><b><span style="font-size:11.0pt"><span new="" roman="" style="font-family:" times="">: </span></span></b>To manufacture PET/ZIF-8 media, after synthesizing ZIF-8, different weight concentrations of it were dissolved in a PET20% solution. Then, the manufactured solutions were transferred to the ESDP30 two-pump electrospinning machine, and based on the defined parameters of the electrospinning machine, PET/ZIF-8 media were produced. The efficiency and pressure drop of the media were measured by the mask and media efficiency and pressure drop test machine at a speed of 10 cm/s (Q=30 L/min). XRD, FTIR, and FE-SEM analyses were used to evaluate the properties of the produced nanofibers.<span lang="FA" dir="RTL" style="font-family:"Times New Roman",serif"></span></span></span><br> <span style="font-size:9pt"><span minion="" pro="" style="font-family:"><b>Results</b><b><span style="font-size:11.0pt"><span new="" roman="" style="font-family:" times="">: &nbsp;</span></span></b>The XRD pattern results were consistent with previous findings, confirming the structure of ZIF-8. The FTIR spectrum of the obtained materials confirmed that the chemical bond structure was consistent with that reported for ZIF-8. The PET/ZIF-8 media (1 wt.%) had an efficiency, pressure drop, average nanofiber diameter, and quality factor of 100%, 320Pa, 171.18&plusmn;37.91 nm, and 0.143 Pa-1, respectively, which performed better than other electrospun PET/ZIF-8 media and HEPA media (type H13).</span></span><br> <span style="font-size:9pt"><span minion="" pro="" style="font-family:"><b>Conclusion</b><b><span style="font-size:11.0pt"><span new="" roman="" style="font-family:" times="">: &nbsp;</span></span></b>According to the results, a concentration higher than 5 wt.% of ZIF-8 resulted in a decrease in the efficiency of the media due to an increase in the diameter of the nanofibers and a decrease in the efficiency of the electrospinning process due to an increase in the solution jet.</span></span><br> &nbsp; ,Polyethylene Terephthalate (PET),Zeolite-8 Imidazolate Framework (ZIF-8),Electrospinning,Filtration,High-Efficiency Particulate air (HEPA) filter 1 12 http://jhsp.medilam.ac.ir/browse.php?a_code=A-10-32-1&slc_lang=en&sid=1 Meghdad Kazemi kazemy.meghdad@gmail.com 1003194753284600238 1003194753284600238 No a) Health and Environment Research Center, Ilam University of Medical Sciences, Ilam, Iranb) Department of Occupational Health Engineering, School of Public Health, Ilam University of Medical Sciences, Ilam, Iran Saba Kalantari MN43519@GMAIL.COM 1003194753284600239 1003194753284600239 No Department of Occupational Health Engineering, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran Farideh Golbabaei mn43519@yahoo.com 1003194753284600240 1003194753284600240 Yes Department of Occupational Health Engineering, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran ali mohamad abbasi am.abbasi@yahoo.com 1003194753284600241 1003194753284600241 No Department of Occupational Health Engineering, School of Public Health, Ilam University of Medical Sciences, Ilam, Iran
