| Quick Determination of CaO and Other Major and Minor Elements in Limestone by ICP-AES |
| In this paper, CaO up to 54% and other major and minor elements in limestone (GBW03105a ) certified reference material using wet digestion were determined with the method of combining internal standard and matrix matching by ICP-AES. Sample recoveries and dilution rates were respectively processed to test minor elements and high content elements. The results were satisfactory with recoveries of 94%~108%, dilution rates of 99.4%~100.2% and stability low 4% (n=6). Experiment data were in very good agreement with certified values. This method was adopted to the analysis of limestone sample in geological survey with the advantages of simple operation, high accuracy, precision and repeatability. |
