| Abstract: | The method for determination of uranium in soft drinking by inductively coupled plasma mass spectrometry (ICP-MS) was established. Sample preparation for different soft drink was investigated and precision and recovery results were evaluated. The relative standard deviations (RSDs) were 1.67%-8.21% (n =6), the spiked recovery were 96.0%-109.0% and the detection limit was 0.010μg ·l~(-1). The method was accurate and reliable. |
