PENGARUH KONSENTRASI ELEKTROLIT, TEGANGAN DAN WAKTU TERHADAP KADAR URANIUM PADA ELEKTROLISIS PEB U3Si2-Al

THE INFLUENCE OF ELECTROLYTE CONCENTRATION, VOLTAGE AND TIME ON URANIUM CONTENT IN THE ELECTROLYSIS OF U3Si2-Al FUEL PLATE. Research on the influence of electrolyte concentration, voltage and time on uranium content in the electrolysis of U3Si2-Al fuel plate has been conducted. In the previous research, electrolysis process of U3Si2-Al fuel plate resulted in the gaining of 4.536 g of U3Si2 powder, in which some of the uranium was dissolved in the electrolyte as a contaminant. If not treated, the dissolved uranium content will increase and may interfere with the subsequent electrolysis process. The uranium contaminant, therefore, needs to be recovered. In this research, during the electrolysis process, sampling of electrolyte was done to determine the uranium content. The experiment showed that a relatively good condition was achieved in the electrolysis process with an electrolyte concentration of 2 N for 90 minutes at 4 volts. In this condition, the uranium content as the contaminant was found to be 125 mg/L. FREE TERMS : uranium contaminant, electrolysis process, electrolyte
