Abstract: Vanadium-aluminum alloy is an important additive for the smelting of high-performance titanium alloys. The accurate determination of elemental contents is of great importance for the smelting process of titanium alloys. In this study, a method for the simultaneous determination of the contents of seven elements(including aluminum, silicon, iron, chromium, molybdenum, yttrium, and phosphorus) in vanadium-aluminum alloys by aqua regia digestion-inductively coupled plasma atomic emission spectrometry(ICP-AES) was established. Al 396.15 nm, Si 251.61 nm, Fe 259.94 nm, Cr 205.55 nm, Mo 202.03 nm, Y 371.03 nm and P 213.62 nm were selected as the spectral lines for aluminum, silicon, iron, chromium, molybdenum, yttrium, and phosphorus, respectively. The linearity of calibration curves of testing elements was good with correlation coefficients(r) all higher than 0.999. The limits of detection in this method were 0.000 3%-0.002 1%(mass fraction, the same below), and the limits of quantification were 0.001%-0.007%. The proposed method was applied for the determination of aluminum, silicon, iron, chromium, molybdenum, yttrium, and phosphorus in actual AlV55 vanadium-aluminum alloy sample. The relative standard deviation(RSD, n=7) of determination results were between 0.50% and 7.8%, and the spiked recoveries were between 96% and 105%.
