Abstract:The optimal condition for determination on trace mercury by flow injection reduction gasification-cold atomic absorption spectrometry was Explored.The flow injection reduction gasification-cold atomic absorption spectrometry analysis method on trace mercury in Cardiocrinum giganteum(Wall.) Makino was established and the detection condition was optimized.The results showed that the method was simple,rapid with high sensitivity and automation.The linear determination range of mercury was 0-80 μg/L,and the relative standard deviation was less than 3.0% with recovery of standard addition of 95%-106%.
Keywords:Cold atomic absorption method  Cardiocrinum giganteum(Wall  ) Makino  Mercury
