Highly efficient and irreversible adsorption of iodine over amine-functionalized ZIF-8 with 3-amino-1,2,4 triazole |
| 초록 |
Considering the serious ill effects of the radioactive iodine (I2) on human health, it is therefore desirable to develop a novel adsorbent for effectively removal of I2. Herein, we reported the synthesis of amine-functionalized ZIF-8 (ZIF8-A) materials with difference amine contents from 15% to 74% by the ligand exchange of 2-methylimidazole with 3-amino-1,2,4-triazole via post-synthetic modification and applied them as adsorbents for I2 capture in n-heptane. Their adsorption performance towards I2 was studied in detail as a function of the contact time, I2 concentration, and reusability. The obtained adsorption equilibrium data were well represented by the Langmuir model and the kinetics were treated with a pseudo-second-order model. A plausible mechanism for the adsorption of I2 on ZIF-8-A adsorbents was proposed by considering the surface complexation and host-guest interaction between Atz ligand and I2 species with electron-transfer from the N atom in the ligand to I atom. |
