Microbial Bioremediation of Uranium01:25

Microbial Bioremediation of Uranium

103
Microorganisms play a critical role in the transformation and immobilization of uranium in contaminated environments through four main pathways: bioreduction, biosorption, bioaccumulation, and biomineralization. These mechanisms reduce uranium’s toxicity and prevent its migration through groundwater systems, offering sustainable approaches for in situ bioremediation.Bioreduction of UraniumBioreduction is driven by anaerobic bacteria such as certain strains of Geobacter and Shewanella,...

The Phosphorus Cycle01:21

The Phosphorus Cycle

35.0K
Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems.

Nuclear Transmutation03:20

Nuclear Transmutation

12.9K
Nuclear transmutation is the conversion of one nuclide into another. It can occur by the radioactive decay of a nucleus, or the reaction of a nucleus with another particle. The first manmade nucleus was produced in Ernest Rutherford’s laboratory in 1919 by a transmutation reaction, the bombardment of one type of nuclei with other nuclei or with neutrons. Rutherford bombarded nitrogen-14 atoms with high-speed α particles from a natural radioactive isotope of radium and observed...

Roles of Electrolytes: Calcium and Phosphate01:27

Roles of Electrolytes: Calcium and Phosphate

4.6K
Calcium and phosphate are essential electrolytes in the human body, with calcium being the most abundant mineral. Around 99% of the body's calcium is stored in the skeleton and teeth, forming a crystal lattice of mineral salts in combination with phosphates. Calcium plays crucial roles in various bodily functions such as blood clotting, neurotransmitter release, muscle tone maintenance, and nervous and muscle tissue excitability.
The calcium concentration in blood plasma is primarily...

Minerals

1.7K
Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.

Other Nuclides: 31P, 19F, 15N NMR01:16

Other Nuclides: 31P, 19F, 15N NMR

888
Many organic, inorganic, and biological molecules contain spin-half nuclei such as nitrogen-15, fluorine-19, and phosphorus-31. As a result, NMR studies of these nuclei have found extensive applications in chemical and biological research.
While fluorine-19 and phosphorous-31 have high natural abundances (100%) and positive gyromagnetic ratios, nitrogen-15 has a low natural abundance and a negative gyromagnetic ratio. However, nitrogen-15 is still preferred over nitrogen-14 (which has a...

Area of Science:

  • Geochemistry
  • Resource Economics
  • Environmental Science

Background:

  • Uranium recovery from phosphate rock has historically underperformed.
  • Market conditions for uranium recovery deteriorated in the 1990s following the Soviet Union's dissolution.

Purpose of the Study:

  • To identify and specify components influencing uranium recovery from phosphate rock.
  • To evaluate current uranium endowments and recoverable amounts from phosphate rock and phosphoric acid production.

Main Methods:

  • A systems approach was employed.
  • Review of past recovery experiences and lessons learned.
  • Identification of key factors determining recovery efficiency.

Main Results:

  • An estimated 5.7 million tonnes of uranium (tU) may be recoverable from phosphate rock reserves.
  • In 2010, recoverable uranium from phosphate rock and phosphoric acid production was estimated at 15,000 tU and 11,000 tU, respectively.
  • This potential recovery could have met the global uranium supply-demand gap for nuclear energy.

Conclusions:

  • The U.S., Morocco, Tunisia, and Russia are identified as prime locations for uranium recovery, considering infrastructure.
  • Future research and sustainability initiatives are highlighted.
  • Long-term contracts with guaranteed prices are essential to ensure profitability and encourage investment in uranium recovery.
