Biomimetic adsorbent efficiently extracts uranium from seawater

The oceans hold an enormous amount of very diluted uranium that could potentially serve as a sustainable fuel source for nuclear power. But how can uranium be extracted quickly and efficiently from seawater? Balancing high selectivity for uranium ions with rapid transport of those ions has long been a major challenge in obtaining uranium from the sea. Now a groundbreaking study suggests a solution. A research team led by Prof. Wen Liping from the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences has developed a biomimetic adsorbent that can attract and hold uranium ions. The inspiration for this adsorbent is the natural porous structure of the spiky, globular fruit of the Chinese sweetgum tree, Liquidambar formosana. The team's findings were recently published in Matter.

Long-used red pigment carmine has a surprisingly complex porous structure

Using advanced electron crystallography techniques, researchers at Stockholm University have succeeded in determining the structure of the historically significant red pigment carmine. It turns out that the substance, used today in products such as candy and paint, has a complex porous structure. The study is published in the journal Crystal Growth & Design. Carmine is a natural red coloring agent produced from cochineal extract. The extract from these insects is rich in carminic acid, which is combined with aluminum (Al) and calcium (Ca) to produce carmine. Analysis using advanced electron microscopy techniques has now revealed that this pigment has an unexpected structure. It is a so-called metal complex, built from two calcium ions, two aluminum ions, and four organic ligand molecules of carminic acid.

New silica-based adsorbent developed for selective separation of radioactive strontium from acidic medium

Prof. Huang Qunying's team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a novel inorganic silica-based adsorbent for the highly selective separation of strontium from acidic medium. The results were published in Separation and Purification Technology. Radioactive strontium (90Sr) is considered to be one of the most dangerous radionuclides due to its high biochemical toxicity. During the vitrification process of high-level liquid waste, the presence of 90Sr can cause instability of the vitrification substrate, resulting in radionuclide leaching. Removal of 90Sr can reduce the heat generation and shorten the cooling time of the vitrification substrate in the repository, which is favorable for further deep geological disposal of the radioactive waste. To address the above issues, Prof. Huang's team developed a novel silica-based adsorbent Sb2O5/SiO2 by a two-step method, i.e., vacuum impregnation followed by oxidation, and investigated the adsorption behavior of the adsorbent on strontium stable nuclide in low and high acid mediums (i.e., pH 6 and 1 M HNO3).

Bio-inspired material targets oceans' uranium stores for sustainable nuclear energy

Scientists have demonstrated a new bio-inspired material for an eco-friendly and cost-effective approach to recovering uranium from seawater.

A research team from the Department of Energy's Oak Ridge and Lawrence Berkeley National Laboratories, the University of California - Berkeley, and the University of South Florida developed a material that selectively binds dissolved uranium with a low-cost polymer adsorbent. The results, published in Nature Communications, could help push past bottlenecks in the cost and efficiency of extracting uranium resources from oceans for sustainable energy production.

"Our approach is a significant leap forward," said coauthor Ilja Popovs of ORNL's Chemical Sciences Division. "Our material is tailor-made for selecting uranium over other metals present in seawater and can easily be recycled for reuse, making it much more practical and efficient than previously developed adsorbents."

Researchers produce 50x more stable adsorbent

A KAIST research team have developed a technology to increase the stability of amine-containing adsorbents by 50 times, moving another step toward commercializing stable adsorbents that last longer.

Professor Minkee Choi from the Department of Chemical and Biomolecular Engineering and his team succeeded in developing amine-containing adsorbents that show high oxidative stability.

The capture of the greenhouse gas carbon dioxide is an active ongoing research field, and some of the latest advancements point to amine-containing adsorbents as an efficient and environmentally friendly way to capture carbon dioxide. However, existing amine-containing adsorbents are known to be unstable under oxidation, which chemically breaks down the adsorbent, thereby making it difficult to rely on amine-containing adsorbents for repeated and continued use.

The researchers have discovered that the miniscule amount of iron and copper present in the amine accelerate the oxidative breakdown of the amine-containing adsorbent. Upon this discovery, they proposed the use of a chelator substance, which essentially suppresses the activation of the impurities.

Professor Cafer T. Yavuz and his team at the Graduate School of Energy, Environment, Water, and Sustainability (EEWS) of Korea Advanced Institute of Science and Technology (KAIST) have developed an adsorbent that can selectively capture soluble organic contaminants in water.

This water treatment adsorbent is a fluorine-based nanoporous polymer that can selectively remove water-soluble micromolecules. It has the added advantage of being cheap and easily synthesized, while also being renewable.

The results of this research have been published online in Nature Communications on November 10, 2016. The research paper is titled "Charge-specific Size-dependent Separation of Water-soluble Organic Molecules by Fluorinated Nanoporous Networks."

Water pollution is accelerating as a result of global industrial development and warming. As new materials are produced and applied in the agricultural and industrial sectors, the types of contaminants expelled as sewage and waste water are also becoming diverse.

Types Of Adsorbents In Industry And Performance Applications

Understanding the types of adsorbents in industry is essential to grasp how different sectors optimize separation processes. Activated carbon remains widely used due to its broad adsorption capacity, especially in water purification and air filtration systems. However, newer materials such as zeolites and alumina-based compounds are gaining traction for their precision in gas separation and catalytic processes.

What makes this segment particularly dynamic is the growing role of hybrid systems.
