MIL series-based MOFs as effective adsorbents for removing hazardous organic pollutants from water

The emergence of hazardous organic pollutants from different industrial processes has a lot of harmful effects on the environment and people's health. Therefore, researchers are paying much attention to finding cutting-edge treatment methods because they are more worried about the environment. Metal-organic frameworks (MOFs), specifically MIL series-based MOFs (MIL = Material Institute of Lavoisier), have gained recognition as promising adsorbent materials for hazardous organics. Because they have unique properties like extraordinary chemical, thermal, and water stability, large pores, unsaturated Lewis's acid locations in some of their structures, and enormously specific surface areas. This makes them the perfect candidate adsorbents for detecting and removing various harmful contaminants, including organic dyes, medical products, herbicides, insecticides, and phenols. This work reviewed the MIL series-based MOFs employed as adsorbents for organic pollutants for the first time. Also, we shed insight on possible adsorption mechanisms, as well as adsorption isotherm, kinetic models, and thermodynamic and regeneration studies of recently reported MILs adsorbents used to uptake organic pollutants. Further, we mentioned MILs history, its synthesis methods, and its merits. Finally, MIL series-based MOFs have provided good stability in the adsorption process, so it is recommended to be an excellent adsorbent platform in the industrial water treatment fields.
