U.S.-Germany Cooperative Research: Speciation of Methylcyclopentadienyl Manganese Tricarbonyl by High Performance-Diode Laser Atomic Absorption Spectroscopy

该奖项支持西卡罗莱纳大学的David Butcher与德国多特蒙德大学光谱化学与应用光谱学研究所的Kay Niemax和Michael Bolshov的合作研究。该研究合作项目将结合高效液相色谱法和二极管激光原子吸收光谱法对甲基环戊二烯基三羰基锰（MMT）燃烧产物中的化合物进行分析。这种燃料添加剂的潜在毒性最近引起了争议，自1995年以来，这种添加剂已在美国作为无铅汽油销售。由于对其燃烧产物的认识不足，与MMT相关的健康风险仍然未知。新的分析技术组合应该能够取代现有分析方法中复杂和昂贵的仪器要求。二极管激光原子吸收技术是在多特蒙德大学开发的，PI将在那里花费两个半星期的时间来评估该方法的灵敏度。鉴于这一努力取得了积极成果，将继续进行合作，以便获得关于硝基甲苯燃烧和毒性的基本资料。

The research cooperative project will couple high-performance liquid chromatography with diode laser atomic absorption spectrometry to analyze the compounds in the combustion products of methylcyclopentadienyl manganese tricarbonyl (MMT). Controversy has developed recently regarding the potential toxicity of the fuel additive, which has been marketed in the United States for unleaded gasoline since 1995. Health risks associated with MMT remain unknown because of insufficient knowledge of its combustion products. The new combination of analytical techniques should be able to replace the complicated and expensive instrumentation requirements of present analytical methods. The diode laser atomic absorption technique was developed at the University of Dortmund where the PI will spend two-and-a-half weeks to evaluate the sensitivity of the method. Given positive results of that effort, collaboration will continue in order to obtain fundamental information regarding the combustion and toxicity of MMT.
