Uranium from the sea

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

“…Since the 1950s, uranium extraction has been studied with a variety of materials such as ion exchangers and adsorbents including titanic acid, lead sulfide, , zinc carbonate, activated carbon, and oxides of titanium, iron, magnesium, and aluminum. , Among all of these, titanium oxide and lead sulfide were considered promising adsorbent materials with higher adsorption capacities of 1.1 and 0.6 mg/g of adsorbent, respectively. Despite the higher adsorption capacity of lead sulfide, it was not easy to keep its surfaces fresh, which resulted in the loss of adsorption capacity .…”
