Analysis of 10 mineral elements in slag by ICP-MS

Inductive coupled plasma mass spectrometry(ICP-MS) was used to analyze the contents of 10 mineral elements in slag.After digested completely by HNO3-HF-HClO4,these samples were determined using the internal method.The recoveries for spiking samples were 78.8%-105.7%,and the relative standard devia-tions were 0.68%-8.29%.The range of the detection limits of elements was 0.002-6.68 μg.g-1.The proposed method is simple,rapid and accurate,and could be used to analyze mineral elements in the slag.
