| Abstract: | Trace magnesium, calcium and strontium in pure water has been determined by inductively coupled plasma atomic emission spectrometry. The effects of nebulizer argon pressure, observation height, and output power on the spectral-line intensity were also studied.The RSDs of three elements are 1.6% - 4.0%.The method is simple,rapid and accurate. |
