- Abstract
In this study, 31 samples were selected from two ice cores collected from Aru and Guriya glaciers in the TP, and four water-soluble metal ions, K+, Na+, Ca2+ and Mg2+, were analyzed and compared with these three instruments to seek for the best analysis scheme. The results show that IC and ICP-MS can both meet the requirements except ICP-OES, especially in K+ analysis. The results were highly consistent, with the correlation coefficients (R²) all above 0.97 and there is no evidence that the measured values from ICP-MS are higher than that from IC. Therefore, in addition to IC, ICP-MS is also an effective method to determine water-soluble metal ions in snow and ice samples from the TP. Meanwhile, the analysis speed of ICP-MS is much faster than IC, and micro and trace elements can also be determined at the same time, which means ICP-MS is very suitable for the rapid analysis of large quantities of ice core samples.
