Adsorbents for the Uranium Capture from Seawater for a Clean Energy Source and Environmental Safety: A Review

“…Uranium extraction has gained more interest for two significant reasons: the increasing demand for uranium as a carbon-free energy source and nuclear waste management as well as its toxicity. − Considering that uranium is limited in terrestrial ores to about 7.6 million tons, various efforts have been made toward the use of unconventional uranium sources such as seawater, which contains 4.5 billion tons of uranium, sufficient to protect nuclear development. , On the other hand, the radioactivity and toxicity of uranium pose a lethal threat to the environment; hence there is a need to develop a sustainable technology to reduce nuclear incidents. − However, it is not easy to extract uranium from seawater, because the uranium concentration in seawater is very low (3 ppb) as compared to other competing metal ions. − Also, the high volume of seawater adds more challenges. ,,, To achieve the targeted goals, a cost-efficient adsorbent with high adsorption capacity, high durability, and fast kinetics has been reported. − …”
