Abstract: The preparation and accelerator mass spectrometry (AMS) measurements of a series of 182Hf AMS calibration standards are described in this paper. The preparation consists of five processes, the synthesis of the initial 182Hf/180Hf standard sample by double neutron capture reaction of 180Hf, the accurate measurement of this standard for isotopic ratio with thermal ionization mass spectrometry (TIMS), the chemical separation of isobaric interference 182W, the sequential dilution of the initial standard, and the preparation of HfF4. The value of 182Hf/180Hf in the initial 182Hf/180Hf standard was obtained with TIMS to be (1.63±0.01)×10-6. Chemical separation and purification procedures were developed and applied in the preparation of all 182Hf/180Hf standards for the removal of major isobaric interference nuclide 182W. As a result, three 182Hf AMS standards with 182Hf/180Hf ratios of (1.63±0.01)×10-6, (3.22±0.26)×10-8, (3.45±0.32)×10-10 were obtained. AMS measurements of these standard samples were performed and good linearity was obtained in a plot of AMS results vs nominal values for 182Hf/180Hf ranging from 1.63×10-6 to 3.45×10-10.
