The large amount of uranium in the oceans could be exploited for nuclear fuel, but existing physicochemical extraction methods are limited in terms of capacity and rates of removal. Here the authors use an electrochemical extraction technique, demonstrating improved uptake capacity and kinetics.
There are over four billion tonnes of uranium in the oceans that could be harvested for nuclear fuel, but current capture methods have limited performance and reusability. Now, an electrochemical method using modified carbon electrodes is shown to be promising for the extraction of uranium from seawater.
