| 摘要: |
| 在使用全谱直读等离子体发射光谱仪分析铅时,发现Cu221.810线对Pb220.3线形成干扰。产生这种干扰的原因是由于全谱直读等离子体发射光谱仪采用了固态阵列检测器和中阶梯光栅,从而在两条谱带之间发生了纵向干扰校正。可以采用干扰系数校正法或者选择在灵敏度稍低的VIS段摄谱进行干扰。 |

| Abstract: |
| A positive interference of copper on lead was found with determination of lead by the full wavelength range direct reading ICP-AES.For instance,the Pb 220.3 line was interfered by the Cu 221.810 line.The interference is generally impossible in that the two lines are far apart for the classical spectrum.The solid-state array detector and echelle grating was applied to the full wavelength range direct reading ICP-AES.The vertical interference was broken out in the two bands.The interference factor correction method or spectrograph in the VIS segment can be used after clearing sources of interference. |
