Silica-based materials offer the opportunity for “selective decoration” where a large variety of adduct, ion exchange and chelate forming organic ligands can be attached directly to the surface. With the correct choice of ligand, in combination with high surface functionalisation, it is possible to offer high sorption capacity, fast exchange kinetics and selectivity for a variety of metal...
Some nuclear accidents and nuclear fuel treatment (such as reprocessing) can release radioactive iodine isotopes, principally 129I and 131I, into gaseous streams and aqueous solutions. Iodine-131 raises concerns in nuclear accidents due to its high activity and the potential for uptake into the human body but does not pose a long-term disposal risk due to its short half-life (t1/2 = 8.04 d)....
The routine monitoring, as a part of radiation protection from radioactive materials released into the environment, is established in many countries worldwide. A radionuclide of particular interest is Sr-90, which is, due to its long half-life, one of the most hazardous radionuclide. As it is pure beta emitter, its isolation prior determination is necessary. In recent years, materials based on...
The sequestering of uranium from the ocean is an attractive choice for clean energy due to its vast inventory (about 4.5 billion tons). In this regard, the extractant with high binding affinity to uranyl (UO22+) is desired. In the past few decades, amidoxime (AO) has been screened as the most promising candidate, and various absorption materials bearing this ligand or its derivatives have been...
Radium is the daughter nuclide of Naturally Occurring Radioactive Materials (NORM), uranium and thorium, which exists in several isotopes. Accordingly it incites great interest in various fields of application such as: environmental monitoring, analytical and medical uses(Gott et al. 2016). Due to its extensive use (in food products, in heating pads and suppositories, in cosmetics, as a...
