摘要: 将目标因子分析用于电感耦合等离子体原子发射光谱分析(ICP-AES)对高纯氧化铥中稀土杂质的测定及光谱重叠干扰校正.数据矩阵由纯光谱矢量、混合物光谱矢量及模型背景矢量构成.提出利用各目标矢量的真误差的平方和为评价函数优化扫描光谱峰位,从而消除扫描式ICP光谱仪发射光谱线的峰位移动给测定带来的影响.

Abstract: Target transformation factor analysis was used to correct spectraLINterference in inductively coupled plasma atomic emission spectrometry(ICPAES) for the determination of rare earth impurities in high purity thulium oxide. Data matrix was constructed with pure and mixture vectors and background vector. Amethod based on an error evaluation function was proposed to optimize the peak position, so the influence of the peak position shift in spectral scans on the determination was eliminated or reduced. Satisfactory results were obtained using factor analysis and the proposed peak position optimization method.

Key words: Inductively coupled plasma, Atomic emission spectrometry, Factor analysis, SpectraLINterference correction, Peak position shift
