Abstract: (24 Views)
Introduction: Production of high-performance media with low pressure drop in air pollution control is an important issue in air filtration. 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.
Materials & Methods: 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.
Results: 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±37.91 nm, and 0.143 Pa-1, respectively, which performed better than other electrospun PET/ZIF-8 media and HEPA media (type H13).
Conclusion: 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.
