| Abstract: | The method for determining the content of trace magnesium and calcium in iron and steel by inductively coupled plasma mass spectrometry is established. Based on this method, the matrix effect is compensated while the stability of determined results is also improved by com- bination of internal standard method and adding calibrating method under the optimal working conditions of the instrument, and thus the recovery rate by this method is in the range of 90.0% to 110.0% and the relative standard deviation is less than 10.0%. By this method the content of trace magnesium and calcium in the iron and steel can be determined quickly and accurately, which can meet the requirements for determining the content of trace magnesium and calcium in the iron and steel in metallurgical industry |
