| Abstract: | In the paper, the inductively coupled plasma atomic emission spectrometry method by which the matrix was matched to the calibration curve was proposed for the direct determination of iron, nickel and chromium in potassium chloride. The optimal analytical wavelength was selected and the background was corrected. The recov ery rate was 90% to 106% .The RSD was below 8.8%. |
