Abstract：After the sample was dissolved with nitric acid (1+1), the content of lead, tin, silicon, zinc, nickel, manganese and iron in aluminum bronze was simultaneously determined by inductively coupled plasma atomic emission spectrometry (ICP-AES) with Pb 220.353 nm, Sn 189.927 nm, Si 251.611 nm, Zn 206.200 nm, Ni 231.604 nm, Mn 260.568 nm and Fe 259.939 as the analytical lines. The influence of matrix elements in aluminum bronze on the determination of testing elements was investigated. The results showed that the influence of matrix effect could be eliminated by the matrix matching method to prepare the calibration curves. The linear correlation coefficients of calibration curves of elements were all higher than 0.999. The detection limits of elements in proposed method were between 0.9 μg/g and 20.8 μg/g. The proposed method was applied to the determination of lead, tin, silicon, zinc, nickel, manganese and iron in certified reference materials of aluminum bronze. The relative standard deviations (RSD, n=10) of determination results were between 0.36% and 4.0%. The results showed no significant difference with the certified values. The content of lead, tin, silicon, zinc, nickel, manganese and iron in two aluminum bronze QAl10-3-1.5 product was determined according to the experimental method. The recoveries were between 90% and 108%.
