| 中文摘要: |
| 采用高分辨电感耦合等离子体质谱法测定地下水中14种稀土元素，并选择Rh作内标，可消除测定中的质谱干扰和非质谱干扰，使方法在0 μg/L~100 μg/L范围内线性良好。方法检出限为0.002 μg/L~0.005 μg/L，实际水样的加标回收率为80.0%~117%，RSD为2.1%~3.8%。 |
| 英文摘要: |
| 14 rare earth elements were detected by high resolution inductively coupled plasma mass spectrometry (HR ICP MS),by choosing Rh as a internal standard,the mass spectral interference and non interference in the detection could be eliminated and the result showed a good linearity in the range of 0 μg/L～100 μg/L.The detection limits of this method were 0.002 μg/L～0.005 μg/L,the recoveries of actual water samples ranged from 80.0% to 117%,and the RSDs were 2.1%～3.8% |
