| 中文摘要: |
| 采用电感耦合等离子体发射光谱法同时测定土壤和水系沉积物样品中Al、Fe、Ca、Mg、K、Na、P、Ba、Be、Cd、Ce、Co、Cr、Cu、Li、Mn、Mo、Ni、Pb、Ti、V、W、Zn等23个常量和微量元素.各元素选择光谱干扰少、准确度高的多向观测方式(轴向、径向、轴向衰减、径向衰减),结合多元光谱拟合技术校正光谱干扰,改善方法的检出限及精密度.结果表明,方法的回收率为94.0%～103.4%,精密度(RSD,n=10)低于3.0%.方法经国家一级标准物质验证,测定值与标准值基本相符. |
| 英文摘要: |
| A method for the determination of 23 macro amount and trace elements， including Al, Fe, Ca, Mg, K, Na, P, Ba, Be, Cd, Ce, Co, Cr, Cu, Li, Mn, Mo, Ni, Pb, Ti, V, W and Zn in soil and stream sediment samples by inductively coupled plasma optical emission spectrometry (ICP-OES) was reported. Multi direction viewing mode (axial, radial, axial attenuation and radial decay) was selected for each element with less spectral interference. The use of multi-component spectral fitting technology for spectral interference correction remarkably improved the detection limits and precision of the method. The recovery was 94.0%~103.4% with the precision of less than 3.0%RSD (n＝10). The method has been applied to the determination of macro-amount and trace elements in National Standard Reference Materials and the results are in agreement with certified values. |
