Adsorption of Geosmin and 2-MIB to Porous Coordination Polymer MIL-53(Al)

Porous coordination polymers (PCPs) are porous materials with large specific surface area and pore ume, and are expected to be used as separation materials for environmental pollutants. The aim of this study was to evaluate the applicability of MIL-53(Al), a type of PCP, f...

description Porous coordination polymers (PCPs) are porous materials with large specific surface area and pore ume, and are expected to be used as separation materials for environmental pollutants. The aim of this study was to evaluate the applicability of MIL-53(Al), a type of PCP, for the separation of geosmin and 2-MIB. The adsorption performance of MIL-53 (Al) for methylene blue and iodine was determined to be lower than that of activated carbon. The time required for the adsorption of musty odorants by MIL-53(Al) was longer than that by activated carbon, and the final adsorption amount was lower than that by activated carbon. Furthermore, adsorption isotherms for the adsorption of musty odorants by each adsorbent were prepared and their adsorption performance was evaluated. The amount of odorant adsorbed by MIL-53(Al) in pure water was extremely low compared to that of activated carbon. On the other hand, the amount of odorants adsorbed by MIL-53(Al) in raw water for water supply was not much lower than that of activated carbon. This study suggests that adsorbents with uniform pore size, such as MIL-53(Al), are less susceptible to interference by other coexisting substances. This finding may be important for future development of adsorbents for musty odorants.
