The contents of iron(Fe),aluminum(Al)and vanadium(V)in titanium alloy were determined by inductively coupled plasma-atomic emission spectrometry(ICP-AES).Dissolve the sample with(1+1)hydrofluoric acid.The mass concentration of the three elements was liner in the range of 0～60 mg/L,the correlation coefficient was 0.999,and the detection limits were 2～5μg/L,the relative standard deviations were 0.52％～2.51％(n=6),and the recoveries were 98％～101％,The relative error of the reference material was 0.5％～1.2％,and the results were satisfactory.
