前言近几年来已有文献报告了用ICP发射光谱直接测定有机溶液样品如油类、酒类等中的多种元素。还有人用螯合萃取的方法对某些痕量元素预先进行富集,然后将有机相直接喷入ICP中进行分析。由于有机溶剂与水相比,在物理性质方面存在很大差异,因而会对ICP产生影响。Greenfield曾报导了将甲醇及其他有机酸引入ICP时,发射强度与溶液粘度,表面张力、密度等物理特性的相关关系。他还报导在以自激式高频发生器作为ICP电源时,有机溶剂
Preface In recent years, there have been reports of ICP emission spectrometry for the direct determination of organic solution samples such as oils, alcohols and many other elements. Some people chelated extraction method of some trace elements pre-enrichment, and then injected directly into the organic phase ICP for analysis. Organic solvents have significant differences in physical properties compared to water, and therefore have an impact on ICP. Greenfield reported the relationship between emission intensity and physical properties such as solution viscosity, surface tension, and density when methanol and other organic acids were introduced into ICP. He also reported organic solvents when using self-excited high-frequency generators as ICP power supplies
