Abstract：The high-chromium cast iron sample was microwave-assisted digested with aqueous regia in a closed vessel. Series standards were prepared with matching Fe matrix and adding Y as internal standard. Line intensities of the prepared standards and the digested sample solutions were determined by inductively coupled plasma atomic emission spectrometry. Accuracy of the proposed method was verified by the analysis of three national standard Materials GSBH 41018, GBW 01120 and GBW 01121, and the results were well agreed with the certification data.
