Abstract (300 words maximum)
The purpose of this project was to create highly adsorbent porous composite materials. Commercially available cotton fabric (CF) with a hierarchical structure contains micro and macro pores. We hypothesized that incorporating a metal-organic framework (MOF) can create highly adsorbent porous material, MOF@CF. Subsequent addition of silver nanoparticles (AgNPs) created AgNP@MOF@CF composite material. In addition, we created AgNP@CF. Such composite material adsorbed and fixed radioactive iodine (based on the following reaction, 2Ag + I2 à 2AgI2). We compared the adsorption and fixation capacity of AgNP@MOF@CF and AgNP@CF. SEM, EDX, FTIR, and XRD techniques were used to characterize the composite materials. The iodine adsorption experiment was monitored by UV-visible spectroscopy. Our iodine adsorption experiment's results indicated the iodine sample containing AgNP@MOF@CF and AgNP@CF had a faster iodine concentration decrease over time compared to the iodine sample containing just CF.
