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%。
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%.
