摘要
镓回收工艺流程中的液体样品经预处理后采用时间分辨紫外脉冲荧光标准加入法测定铀含量。方法最低检出限为0.1μg·mL-1,测定结果相对标准偏差为2.7%,与ICP-MS法比对结果吻合。方法响应速度快,操作简单,适合镓回收工艺流程中微量铀的快速检测。
A new method was established to detect the trace uranium in gallium bearing solution in Bayer alumina hydrometallurgy by adding standard Time-Resolved UV-Induced Fluorescence. The LOD of the method is 0. 1 μg · mL- 1, and a RSD o5 2. 7% was achieved by ten times determination o[ uranium of 4 μg· mL-1 in gallium bearded solution. The detecting results was in good agreement with that of ICP- MS. The method is fast, cheap and easy in operation, there for it is applicable for the rapid determina- tion of uranium in gallium recovery process and other mining ＆ metallurgy technology.
