Selective Removal of Cesium and Strontium from Aqueous Radioactive Waste
This community develops materials and methods to selectively capture radioactive cesium and strontium ions from liquid waste streams, primarily using ion exchange and adsorption techniques.
The research focuses on synthesizing specific sorbents to isolate these radionuclides from complex aqueous solutions. Recurring materials include zirconium phosphate, titanium phosphate, and prussian blue analogues such as copper hexacyanoferrate. The work emphasizes high selectivity and efficiency in removing cesium and strontium from contaminated water, often utilizing composite materials, zeolites, and graphene oxide. Applications center on treating liquid radioactive waste and decontaminating water sources, with a strong emphasis on the chemical mechanisms of ion exchange and adsorption in acidic or neutral aqueous environments.
The largest share of the community's output is found in strontium research, accounting for 3.3% of all strontium research, and 1,976 papers here. Phosphorus and zirconium also contribute significantly, representing 0.6% and 1.2% of their respective element research, with 2,095 and 2,069 papers in this group.
There are 16,310 papers in this community, published most frequently in the Journal of Radioanalytical and Nuclear Chemistry, Separation Science and Technology, and the Journal of Hazardous Materials.
Recent work continues to explore advanced separation techniques, including zeolite-based separation of radioactive nuclides and electrochemically switched ion exchange for radiostrontium uptake. Other recent studies examine the extraction of cesium from weak alkaline solutions using synergistic solvent systems and the development of nanocomposite hydrogels for adsorption.
