New electrochemical method for separation of the iodine-131 radiopharmaceutical produced from uranium-235 fission
An alternative method based on electrochemical techniques for separation and purification of iodine in the presence of ruthenium, molybdenum, and tellurium, which are some elements resultants from uranium fission reaction, is proposed. For this, all elements were electrochemically characterized using the cyclic voltammetry technique. All the characterization and separation were performed using different parameters, such as temperature, pH, concentration, and potential, aiming to determine the optimized operation conditions to achieve the highest separation yield. The highest iodine yields were observed in acidic medium, at 298 and 313 K, and in lower iodine concentrations, which resulted in a separation rate of 45%. On the other hand, the iodine separation in basic medium resulted in very poor yields, indicating that the separation is not efficient in pH > 8.
期刊介绍：
The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry.
The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces.
The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis.
The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
