Abstract：The detection of 19 kinds of elements is required in standards of titanium and titanium alloy product. At present, in current related standard methods in China, however, only one or few elements can be detected once. If multiple elements are measured at the same time, it takes a lot of time and the detection cycle is long. In the experiments, the sample was treated by microwave digestion in HCl-HF-HNO3-HClO4 system. The matrix matching method was used to eliminate the influence of matrix effect. The spectral interference of some elements was solved by combining with multispectral fitting (MSF) correction technology. The contents of Fe, Si, Mn, Mo, B, Al, Sn, Cr, V, Zr,Mg, Nb, Pd, Ni, Ta, W, Ru, Cu and Nd in titanium and titanium alloys were determined by inductively coupled plasma emission spectrometry (ICP-AES). The analysis method for the simultaneous determination of 19 elements in titanium and titanium alloys by ICP-AES was established. Within the linear range of each element, the linear correlation coefficients of calibration curves were all above 0.998. The limits of quantification of elements were between 0.001% and 0.005%. The contents of 19 elements in titanium alloy sample were determined according to the experimental method. The relative standard deviations (RSD, n=7) of determination results were less than 5.0%. The spiked recoveries ranged from 95% to 102%.
