Description
Summary: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. •Time, current, electrolyte volume and anode-cathode distance were studied.•Three electrolyte solution-cathode material systems were investigated.•pH and temperature conditions during the electrodeposition were monitored.•Optimized electrodeposition parameters for each system are provided.•The results are evaluated for usage in determination of actinides (U, Pu, Am, Cm).
