Abstract
Water scarcity and pollution are serious environmental problems and global concerns that affect millions of people. For this reason, there is increasing demand for frequent water quality monitoring. Therefore, there is a need for the development of efficient analytical platforms and methodologies that combine high accuracy, affinity, sensitivity, and selectivity towards various pollutants. Metal-organic frameworks (MOFs) have emerged as promising adsorbents, stationary phases, supports, and active coating for pollutant detection, extraction, sample clean-up, and separation. This chapter summarises the recent advances and trends in the application of MOFs in various analytical methodologies such as solid-phase extraction, solid-phase microextraction, and electrochemical sensors. A brief discussion of the synthesis strategies and their incorporation into various nanomaterials to increase the affinity of the resultant adsorbent towards various analytes is made. The application of MOF-based adsorbents for
extraction, preconcentration, separation, and detection of pollutants in
water systems is reported.
