摘要
采用将喷气燃料中的元素硫与汞反应转化生成汞的化合物后由冷原子吸收法测汞的方法 ,获得油样中元素硫含量。此法灵敏度高 ,元素硫最低检测浓度为 1.6× 10 - 3 μg /ml;元素硫浓度在 0～ 0 .0 5μg/ml范围内与紫外光吸收值存在良好线性关系 ,方法精密度和准确度好。
In order to measure the elemental sulfur in jet fuel,the method can be used,that is the elemental sulfur in jet fuel reacts quantitatively with mercury to produce mercury sulfide,and then the mercury content in mercury sulfide is measured by atomic absorption spectrophotometry.This measurement method possesses high sensitivity,good precision and accuracy,the minimum detectable concentration of elemental sulfur is 1.6×10~ -3μg/ml,and the linear range of elemental sulfur is 0 to 0.05 μg/ml.
