高铬铸铁样品经微波消解， 以氧化钇为内标， 用电感耦合等离子体发射光谱法同时测定样品溶液中的铬、 镍、 铜、 锰、 磷、 硅、 钼和钛。 分析了3种有证国家标准物质， 测定值同证书值吻合， 验证了方法的准确性。

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.
