| 中文摘要: |
| 采用碱熔-水浸法溶解难溶钌靶废料，研究熔剂种类、碱熔条件和水浸条件对钌溶解率的影响。结果表明，以Na2O2和NaOH组成的熔剂具有较高的碱熔效率；在配料质量比为Na2O2:NaOH:Ru= 4:3:1的条件下，750℃碱熔3 h得到碱熔渣；在液固比为150:1 mL/g，95℃以水浸取碱熔渣4 h，钌靶废料的溶解率达到97.3%。 |
| 英文摘要: |
| 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%. |
