Extracting Uranium From Seawater

Chemical & Engineering News Archive, 2012
If, like most scientists, you haven’t thought much about the composition of seawater, it may come as a surprise that the oceans contain uranium. In fact, they hold a staggering quantity of the heavy element. “It’s estimated that more than 4 billion metric tons of uranium are dissolved in the Earth’s oceans,” according to Benjamin P.

Constructing an Ion Pathway for Uranium Extraction from Seawater

Chem, 2020
Summary Uranium extraction from seawater is a major barrier for the development of nuclear power to cope with the energy and climate-change crises. Here, we report the integration of conductive chains into porous adsorbents, which provide the expended electric field to cover the micrometer-sized adsorbent particles under alternating currents.

Self-Assembly Approach for Uranium Extraction from Seawater

Inorganic Chemistry
Efficient uranium extraction from seawater remains a highly challenging task due to the lack of an available approach to access a precise uranium-identified site in the adsorbent. To this end, we demonstrate herein a novel in situ self-assembly approach by directly using two organic molecules, 2,6-pyridinedicarboxaldehyde and terephthalohydrazide, to ...

Porous frameworks for uranium extraction from seawater

Chemical Synthesis
The utilization of uranium (U) fission energy as a high-density, clean power source plays a pivotal role in mitigating greenhouse gas emissions. Uranium extraction from seawater exhibits superior environmental friendliness compared to terrestrial uranium mining, as it avoids substantial generation of radioactive waste and harmful chemicals.

Application of Natural Antibacterial Plants in the Extraction of Uranium from Seawater

ACS Applied Bio Materials
Marine biofouling directly affects the performance and efficiency of uranium (U(VI)) extraction from seawater. Compared to traditional chemical methods, natural plant extracts are generally biodegradable and nontoxic, making them an environmentally friendly alternative to synthetic chemicals in solving the marine biofouling problem.
