Effective Adsorption of Radioactive Iodine by Fabrication of Porous Composite Materials

Commercially available cotton fabric (CF), where each fiber contains nanopores and the hierarchical structure contains micro and macropores. CF is the ideal skeleton material, with high porosity and average elasticity. The above properties make this material with high absorption capacity characteristics. We hypothesize that chemically incorporating a porous metal-organic framework (MOF) into the porous CF material will create a highly adsorbent porous composite material. The MOF immobilization on CF will create a MOF@CF composite. This will be subsequently loaded with silver nanoparticles (AgNPs) on the MOF, creating AgNP@MOF@CF composite material. Such material will adsorb and fix molecular iodine as AgI@MOF@CF (based on this reaction, 2Ag + I2 à 2AgI). SEM, EDX, FTIR, and XRD techniques will be used to characterize the composite materials. The iodine adsorption experiment will be monitored by UV-visible spectroscopy
