Abstract：The accurate determination of impurity elements in pure ruthenium was of great significance to the properties and processing technology of ruthenium powder products. The ruthenium matrix had serious interference with the determination of most impurity elements, so accurate results were hardly directly measured. Pure ruthenium sample was digested in hydrochloric acid-potassium chlorate system under high temperature and high pressure conditions. The ruthenium matrix in sample was removed by perchloric acid fuming to eliminate the matrix effect. Total 26 impurity elements (including Pt, Pd, Rh, Ir, Au, Al, As, Be, Bi, Ca, Cd, Co, Cu, Fe, Mg, Mn, Na, Ni, Pb, Sn, V, Zn, Mo, Ti, Ga and Zr) in pure ruthenium was determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). The concentration of elements in range of 0.10-10μg/mL was linear to the emission intensity with correlation coefficients higher than 0.9995. The detection limits of method ranged from 0.00006 to 0.012μg/mL. Twenty-six impurity elements in pure ruthenium powder were determined according to the experimental method. The relative standard deviations (RSD, n=5) of determination results were in range of 1.1%-9.7%. The spiked recoveries were between 89% and 109%. The impurity elements in ruthenium powder sample were determined according to the experimental method, and the found results of most elements were consistent with those obtained by glow discharge mass spectrometry (GD-MS).
