| Abstract: | 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. |
