Abstract

In the present study, the synthesis and identification of the suitable nanostructured adsorbent to reduce or eliminate the odorant smell spread in air in an accidental situation were done. In this regard, various samples of carbon, zeolite and metal-organic framework adsorbents were prepared and adsorption of odorant over these samples was measured. According to the obtained results, the adsorption power of the tested adsorbents in low concentration of odorant was as follows:
UiO-66 (Zr)> MIL-101 (Cr)> MOF-199 (Cu)> MIL-53 (Al)> Cu-AC> MIL-53 (Cr)> AgX> AgY> NaX> AC> CuY> NaY > CuX> MIL-101 (Fe)
Then the selected adsorbents include Cu-AC, NaX, MIL-101 (Cr) and UiO-66 (Zr) which showed good adsorption performance were investigated in higher concentration of odorant. The results showed that the adsorption power of UiO-66 (Zr) was approximately 3.3 times of Cu-AC and 7 times of NaX. According to the experimental and economic studies conducted in this study, NaX and Cu-AC can be considered as suitable candidates for removing the odorant in accidental situations.
