Abstract：The conditions for the determination of titanium in zirconium and zirconium alloys by inductively coupled plasma atomic emission spectrometry (ICP-AES) was explored and the determination method was established. Hydrochloric acid, hydrofluoric acid and nitric acid were selected to dissolve the sample, the spectral lines of wavelength 339.4 nm (without niobium in the sample) or 338.3 nm (with niobium in the sample) were used as the analytical lines for titanium, and under the selected operating conditions of the instrument, titanium in the analyte solution was measured. Tin, iron, chromium and nickel didn’t affect the determination of titanium. The impact of the matrix element zirconium and the alloy element niobium on the determination of titanium could be removed by matrix matching and the selection of a different wavelength spectral line as the analytical line for titanium. Under the selected working conditions of the instruments, the content of titanium in zirconium and zirconium alloy samples was measured several times, and the results were consistent with those obtained by the spectrophotometry (GB / T13747.1992) and direct-current arc atomic emission spectrometry, the relative standard deviation (n = 9) being less than 15%. Both the precision and accuracy of the method could meet the testing requirements in research and production.
