| 中文摘要: |
| 用王水对含铱树脂中的铱进行造液处理。实验表明，金属铱的溶解率可达90%，且金属基本不会损失。考察了王水浓度、加热温度、保温时间、料液比对于铱溶出率的影响；在王水浓度为80%，加热温度在85 ℃，保温时间为1.5 h，料液比为1:3的最佳条件下，金属铱的溶出率可达90%。 |
| 英文摘要: |
| Use aqua regia to treat the iridium in the iridium containing resin. Experiments have shown that the dissolution rate of metal iridium can reach 90%, and the metal will not be lost. The effects of aqua regia concentration, heating temperature, holding time, and material liquid ratio on the dissolution rate of iridium were investigated; Under the optimal conditions of 80% aqua regia concentration, heating temperature at 85 ℃, holding time of 1.5 hours, and a material liquid ratio of 1:3, the dissolution rate of metallic iridium can reach 90%. |
