| 摘 要： | 研究了ICP光源中正丁醇对水样品溶液物理性质(表面张力、粘度)及雾化特性的影响,观测了元素Fe、Si、V和Sr的发射强度和信背比,并且用ICP发射光谱法测定了自来水中痕量元素Pb和Cd.结果表明,有机溶剂正丁醇能够改变试液物理性质,提高雾化效率,增强光源辐射强度;元素Pb和Cd的RSD分别为5.84%和7.41%,回收率分别为94.3%和92.7%.

| Abstract: | The effects of 1-Butanol on the physical properties(surface tension,viscosity)and nebulization of sample solution in the ICP were studied.Emission intensity and signal-to-background ratio of Fe,Si,V,and Sr were observed.The trace elements of Pb and Cd in water were determined using the ICP-AES.The experimental results showed that the organic solvent 1-Butanol changed physical properties of sample solution,improved efficiency of nebulization and enhanced radiant intensity of the source.RSDs of Pb and Cd are 5.84% and 7.41% with recoveries of 94.3% and(92.7%,)respectively. |
