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F e、S i、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%。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.
