Abstract：The sample was fused with potassium hydroxide-potassium nitrate in muffle furnace at 500-550℃ for 1h. After leaching the melt with hot water, hydrochloric acid was added for acidification. Ru 240.272nm and Ir 212.681nm were selected as the analytical lines. The influence of matrix effect was eliminated by preparing standard solution series with matrix matching method. The content of ruthenium and iridium in solution was determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). Thus, a determination method of ruthenium and iridium in metal anode coating by ICP-AES was established. As the mass concentration of ruthenium and iridium was in range of 0.50-10mg/L, the linear correlation coefficients of calibration curves were higher than 0.999, and the detection limit of ruthenium and iridium was 0.03g/m2 and 0.09g/m2, respectively. The content of ruthenium and iridium in metal anode coating sample was determined according to the experimental method. The relative standard deviation (RSD, n=10) was 0.69% and 1.5%, respectively. The results were basically consistent with those obtained by atomic absorption spectrometry (AAS).
