Abstract：Zirconium-hafnium alloy has excellent properties and it has been widely used. The chemical composition of zirconium-hafnium alloy should be determined accurately. The sample was dissolved with 10mL of hydrochloric acid-2mL of hydrofluoric acid-1mL of nitric acid. P 178.221nm, Fe 239.562nm and Hf 277.336nm were selected as the analytical line. The background was deducted by two-point correction method. The determination method of phosphorus, iron and hafnium in zirconium-hafnium alloy by inductively coupled plasma atomic emission spectrometry (ICP-AES) was established. The calibration curves of elements had good linearity and the correlation coefficients were all higher than 0.999. The determination range of the method was 0.002%-0.036% for phosphorus, 0.01%-0.36% for iron and 1.00%-5.00% for hafnium, respectively. The limit of detection of elements were in range of 0.000032%-0.0019% (mass fraction). The contents of phosphorus, iron and hafnium in one zirconium-hafnium alloy sample were determined according to the experimental method. The relative standard deviations (RSD, n=10) of determination results were less than 3%, and the recoveries were between 94% and 107%.
