| The influence of flux type, alkali fusion and water immersion conditions on the dissolving rate of ruthenium was studied. The results showed that the flux composed of Na2O2 and NaOH had a higher alkali melting efficiency. Under a mass ratio of Na2O2: NaOH: Ru = 4:3:1, the mixture was melt at 750℃ for 3 hours, then the obtained alkali slag was extracted by water immersion at 95℃ for 4 hours with a liquid/solid ration of 150:1 mL/g, and the dissolution rate of ruthenium target waste was 97.3%. |
