摘　　要：用ICP-AES方法直接测定了纯净水(144KΩ·cm)中痕量元素Mg,Ca和Sr,并研究了载气压力、观测高度和输出功率等实验条件对谱线强度的影响。光谱分析的相对标准偏差(RSD)在4％以内,方法简便、快速、准确。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.
