摘要：

Trace levels (pg kg(-1)) of Am-241 in sediments were determined by isotope dilution high resolution inductively coupled plasma mass spectrometry (1D HR ICP-MS) using a microconcentric nebulizer. Am-241 was isolated from major elements like Ca and Fe by different selective precipitations. In Further steps, Am was first separated from other transuranic elements and purified by anion exchange and extraction chromatography prior to the mass spectrometric measurements. The ID HR ICP-MS results are compared with isotope dilution alpha spectrometry. (C) 2001 Elsevier Science Ltd. All rights reserved.
