Although water is considered a renewable resource by rainfall, its availability is finite in terms of time and location. Closely associated with the overall availability of water is the problem of water pollution and human diseases. Of particular concern are the emerging organic contaminants, including pharmaceuticals, pesticides, veterinary products, or plastics, among others. These pollutants can severely affect the environment as well as the animal and human health.1 Despite several strategies have been proposed for the EOCs exclusion, their insufficient removal of these processes in wastewater treatment plants (WWTPs) makes necessary to search new efficient alternatives for water remediation. Similarly, disinfecting water is one of the most important processes in drinking water treatment plants (DWTPs) to control waterborne diseases transmission. Chlorination is the most commonly used process but it could lead to the formation of hazardous inorganic by-products (ClO2- and ClO3-). 2 In this context, metal-organic frameworks (MOFs) have emerged as promising candidates for water treatment. 3 Here, some recent examples of their performances on challenging topics will be presented, including: i) plastic degradation, ii) pharmaceuticals removal in wastewater; iii) agrochemical-based MOFs; iv) H2 production; and, v) purification of disinfected potable water.4 Acknowledgments.
