Abstract:

Partial least square method (PLS) is the multivariate statistical method on the basis of factor analysis. At present, the application of PLS in analytical chemistry is widely seen and its applied prospect has been shown. It is scarcely seen that the application of PLS in flame atomic absorption spectrometry(FAAS) because people have the trouble that in the range of less than nanometer want to choose observational points of more than decades. We have recently overcome the trouble. At the present paper, we continue using PLS to compensate for the spectral overlap interference of Eu 324.75nm with Cu 324.754nm in rare earth oxide.
