The separation and simultaneous determination of the traces of U and Th in seawater by IDMS is described.The detection limits of this method are 2.4×10-9 g for Th and 1.1×10-8 g for U.The concentrations of U and Th in seawater nearby Xiamen were measured,which are 3.20 ppb and 7.73 ppt respectively.The precisions fo the method are ±1.7% for U and ±3.6% for Th respectively.
