CORRECTION OF SPECTRAL INTERFERENCES IN INDUCTIVELY COUPLED PLASMA ATOMIC EMISSION SPECTROMETRY WITH A MODIFIED CHEMOMETRIC METHOD BASED ON MATRIX PROJECTION

本文将矩阵投影算法应用于ＩＣＰ－ＡＥＳ中光谱干扰的校正。在有关文献方法基础上，对残差作了进一步的校正，并采用最优化技术确定背景光谱的最优解，因而提高了方法的准确度。对实际干扰体系的校正结果表明，本方法能够对ＩＣＰ－ＡＥＳ中比较复杂的结构背景以及谱线重叠干扰进行较为准确地校正。

A modified chemometric method based on matrix projection was developed to correct the spectral interferences in inductively coupled plasma atomic emission spectrometry(ICP AES).The accuracy of the correction was significantly improved by reevaluating the residuals.The excellent analytical results for some rare earth elements proved the method fairly feasible.
