Surface functionalized nanostructured ceramic sorbents for the effective collection and recovery of uranium from seawater.
The ability to collect uranium from seawater offers the potential for a nearly limitless fuel supply for nuclear energy. We evaluated the use of functionalized nanostructured sorbents for the collection and recovery of uranium from seawater. Extraction of trace minerals from seawater and brines is challenging due to the high ionic strength of seawater, low mineral concentrations, and fouling of...
متن کاملCurrent status of technology for collection of uranium from seawater
Total amount of uranium resource in seawater is one thousand times of that in terrestrial ores. A polymeric adsorbent being capable of collecting uranium in seawater was developed in early 1980s, since uranium is inevitable resource to operate atomic power plants. This adsorbent fabric was synthesized by radiation-induced graft polymerization which could impart a desired functional group into f...
متن کاملExtraction of uranium from seawater: a few facts
Although uranium concentration in seawater is only about 3 micrograms per liter, the quantity of uranium dissolved in the world’s oceans is estimated to amount to 4.5 billion tonnes of uranium metal (tU). In contrast, the current conventional terrestrial resource is estimated to amount to about 17million tU. However, for a number of reasons the extraction of significant amounts of uranium from ...
متن کاملCharacterization of uranium(V1) in seawater’
The physicochemical characterization of uranium(V1) in seawater is described on the basis of species distribution calculations and experiments using polarography and spectrophotometry in artificial seawater at elevated uranium concentrations. Various dissolved uranium(W) species are identified under different conditions of pH and carbonate concentration. Below pH 4, the hydrated uranyl ion is p...
متن کاملToxicological Investigation of Radioactive Uranium in Seawater
Trace uranium detection measurement was performed using DNA immobilized on a graphite pencil electrode (DGE). The developed probe was connected to the portable handheld voltammetric systems used for seawater analysis. The sensitive voltammogram was obtained within only 30 s accumulation time, and the anodic stripping working range was attained at 100~800 μg/l U and 10~50 μg/l. The statistic rel...
