将无机汞、甲基汞、乙基汞、苯基汞等4种形态汞 ,经葛氏试剂衍生为相应的正丁基衍生物后 ,在弱极性SE -54熔融石英毛细管柱上研究了其衍生物的色谱行为。在优化的色谱条件下 ,4种形态的汞在9min内达到基线分离。此外 ,提供了4种形态汞的正丁基衍生物的电子轰击质谱信息。Four important Hg species in environment, including inorganic, methyl_, ethyl_ and phenyl _ mercury, were derivatized by using n _ butyl Grignard reagent. Under the optimal chromatographic conditions, the resulting derivatives were separated completely on an SE-54 fused silica capillary column within 9 min. In addition, the EI (70 eV) mass spectra of the n _ butyl derivatives of four mecury species are presented.
