| 摘 要： | 通过标准加入法运用电感耦合等离子体原子发射光谱(ICP-AES)定量分析饮用水中Na、Pb元素的含量.在饮用水中加入适当含量的有机溶剂甲基异丁基甲酮(MIBK)可提高谱线强度.实验结果表明,有机溶剂MIBK能够改变试液的物理性质,提高物化效率,增强光源辐射强度,元素Na和Pb的RSD分别为8.24%和11.34%,回收率分别为107%和110%.

| Abstract: | By the method of standard addition,the inductively coupled plasma atomic emission spectrometry（ICP-AES） was used to analyze the contents of Na,Pb in drinking water.The appropriate organic solvent MIBK was added into drinking water to improve the intensity of spectral line.Experimental results show that the MIBK solvent can change the physical properties of test solution,improve physical and chemical efficiency,and enhance the intensity of light radiation.The source RSD of Na and Pb were 8.24% and 11.34%,with recoveries of 107% and 110%,respectively. |
