A method for determination of trace elements in uranium ore concentrates by high resolution inductively coupled plasma mass spectrometry (HR-ICP-MS) was developed. Results obained by the method can be used to identify origins, processing characteristics and quality of uranium ore concentrates. The sample was dissolved by 2% nitric acid and prepared to matrix concentration of 1 g·L－1, followed by the measurement of HR-ICP-MS with on-line internal standard technique. The contents of multi trace elements from 7Li to 232Th have been determined, giving about 16% of relative deviation over certified reference material. The method has been validated using certified reference material. 相似文献
