Water pollution is a growing threat as contaminants accumulate in aquatic ecosystems. Conventional cleanup methods often struggle to achieve adequate purification because of their low uptake capacity. Metal-organic frameworks have emerged as promising alternatives to traditional porous materials, offering enhanced selectivity and higher adsorption capacities. These materials possess high surface areas and adaptable chemical functionalities, enabling the design of novel adsorbents tailored to isolate specific water pollutants. Recent advances over the past five years demonstrate the application of metal-organic frameworks across diverse water treatment scenarios, evaluated through task-specific adsorption performance. Looking ahead, these porous structures present distinct opportunities for future water purification technologies, although their real-world implementation relies on continuing developments to optimise pollutant removal from contaminated water sources.
Water contamination poses severe risks to ecosystems and human health, demanding more efficient filtration methods. Traditional materials often fall short in capturing complex or dilute hazardous substances. Understanding how metal-organic frameworks perform as advanced adsorbents helps guide the development of cleaner, more reliable water treatment systems capable of addressing persistent pollution challenges.
The technology focuses on water treatment adsorbents for environmental management and industrial water purification. The work appears to be at an early to intermediate stage of research, assessing five years of laboratory-scale adsorbent performance and future opportunities rather than deployed systems. Adsorbent manufacturers and municipal or industrial wastewater operators could eventually utilise these materials if scalable synthesis and deployment challenges are addressed.

Water contamination is an increasing concern to mankind because of the increasing amount of pollutants in aquatic ecosystems. To purify the polluted water, various techniques have been used to remove hazardous components. Unfortunately, traditional cleanup techniques with a low uptake capacity are unable to achieve water purification. Metal-organic frameworks (MOFs) have recently shown potential in effective water pollutant isolation in terms of selectivity and adsorption capacity over traditional porous materials. The high surface area and versatile functionality of MOFs allow for the development of new adsorbents. The development of MOFs in a range of water treatments in the recent five years will be highlighted in this review, along with assessments of the adsorption performance relevant to the particular task. Moreover, the outlook on future opportunities for water purification using MOFs is also provided.
