ABSTRACT
Adsorption studies of miscellaneous organic compounds from water are conducted with the aim of purification of water from spilled liquid fossil fuels and various by-products of industrial organic chemical synthesis. MIL-101(Cr) (F) is well-known to be stable in liquid water at room temperature, so this metal-organic framework (MOF) is promising for adsorption-based applications. For adsorption of Perfluorooctanoic Acid (PFOA) in water by mesoporous MOFs, the ionic mechanism has been contemplated, which would require positively charged functional groups in the MOF sorbent. The toxicology studies on animals indicate that PFOA can cause several types of tumors and neonatal death and may have toxic effects on the immune, liver, and endocrine systems, and there is evidence of its toxicity to humans as well. The adsorptive removal of chlorinated aromatic compounds from water by water-stable mesoporous MOFs seems to be an effective approach, since mesoporosity favors the adsorption of larger molecules, which feature the highest toxicity.
