摘　　要：本文提出了一种用于ICP－AES的自适应分析新方法，与现有方法不同，能直接估计出样品中各组分的含量值，其背景参考的选择与谱图无关。新方法的性能由模拟和实测谱图的分析结果得到验证。This paper proposes a new adaptive analysis method for ICP-AES, which can handle background and spectral overlap interferences. It is different from the traditional method in that the component concentration values of a sample can be estimated directly by adaptive filtering and the selection of background references is independent of spectra. The power of the new method is illustrated with simulated and real spectra.
