Investigation of key factors in preparation of alpha sources by electrodeposition

Abstract

The electrodeposition for alpha source preparation, using several electrolyte solution-cathode material combinations, is investigated and evaluated. The investigated factors focused on the electrodeposition time, the applied current, electrolyte volume and anode-cathode distances for the conventional electrodeposition cell (with no external stirring or cooling system). The conditions (temperature and the solution pH) during the electrodeposition process were also studied and discussed. The optimized parameters for each system are provided, and evaluated for the usage in determination of actinides (uranium, plutonium, americium and curium radioisotopes) in various samples.

Electrocatalytic Performance of V2O5/Ti Composite Membrane for High-Efficiency Treatment of Ammonia Nitrogen Wastewater

“…Compared to our previous studies on catalysts TiO 2 and MnOx, V 2 O 5 is widely used in lithium-ion batteries, [28][29][30] supercapacitors, 31,32 gas sensitive sensor, 33,34 electrochromic materials 35,36 and catalytic destruction of hazardous organic compounds [37][38][39][40] owing to its abundant valence state (+2, +3, +5) as well as various chemical structures. 41 Researchers mainly adopted the sol-gel, 42 electrodeposition, 43 hydrothermal, 44 and magnetron sputtering 45,46 methods to prepare V 2 O 5 films. Due to its dense and uniform structure as well as excellent adhesion forces between the coating and substrate, the coating prepared by the magnetron sputtering method has received widespread attention.…”

Overcoming Diffusion Mass Transfer Barriers by Surface Electro-Precipitation (SEP)

“…Since the first report by Meitner in 1911, 35 SEP has mainly been used in α-radiometry to deposit thin continuous actinide oxide layers from solutions containing ultratraces of actinides. 21,28 SEP has also been observed for heavy metals in microbial fuel cells (MFCs) 36,37 and CDI. 38 It has been known for more than a half a century that SEP can separate Y from Sr, as well as actinides from Al, Ti, and heavy metals.…”

Potential Application of Ionic Liquids for Electrodeposition of the Material Targets for Production of Diagnostic Radioisotopes

“…For instance, Oh et al [22] examined ammonium chloride, ammonium oxalate and ammonium sulphate as the electrolyte solutions for U, Pu and Am deposition. Krmpotića et al [23] described the procedures leading to obtain alpha sources from acidified (pH~2) aqueous solutions of sulfates or oxalates. For uranium these conditions can be suitable for oxide layer formation, however the applications to alpha spectroscopy preclude formation of thick targets.…”
