Metal-organic frameworks as remedy for water pollution – sensing and removal

Abstract

The use of several MOFs for water sensing and adsorptive removal of toxic chemicals from water is explored. In the first chapter, the synthesis, properties, and applications of MOFs were discussed. The second chapter illustrates the application of a zinc MOF with nitrogen binding sites for the sensitive and selective sensing of mercury ions was explained. In the third chapter, we have shown that the fragment of benzene tricarboxylic acid in a Ba-based MOF was replaced by boronic isophthalic acid in situ to obtain a series of MOFs. The modified MOFs were used for cis-diol adsorption in an aqueous medium. In the fourth chapter, the usage of a zinc MOF as solid-phase microextraction (SPME) coating for the extraction of polycyclic aromatic compounds (PAHs) is explained. The fifth chapter illuminates the thiol functionalised zirconium MOF template for the synthesis of palladium nanoparticles in the narrow size range and its use as a catalyst for hexavalent chromium reduction in an aqueous medium.
