AB  - For environmental protection from exposure to airborne toxic gases, metal organic 
      frameworks (MOFs) have drawn great attention as gas adsorbent options, with their 
      advantages in chemical tailorability and large porosity. To develop a fiber-based 
      gas filter that is effective against SO(2) gas, zeolite imidazole framework-8 
      (ZIF-8) was applied to polypropylene nonwoven by various methods. Among the 
      tested methods, the sol-gel impregnation method showed the highest ZIF-8 loading 
      efficiency. There existed an optimal loading of ZIF-8 for the maximum adsorption 
      efficiency, and it was associated with the accessibility of gas molecules to the 
      ZIF-8 pores and active sites. Dominant adsorption processes and mechanisms were 
      investigated by fitting the theoretical sorption models to experimental data. The 
      results demonstrate that the increased ZIF-8 loading to fibers, beyond a certain 
      level, may hinder the diffusivity and increase the barrier effect, eventually 
      decreasing the adsorption efficiency. This study is novel and significant in that 
      a multifaceted approach, including experimental analysis, theoretical 
      investigation, and computational modeling, was made for scrutinizing the 
      intricate phenomena occurring in the gas sorption process. The results of this 
      study provide the fundamental yet practical information on the manufacturing 
      considerations for the optimal design of MOF-loaded fibrous adsorbents.
