MTB分光光度法检测汽油中的微量铅

DETERMINATION OF TRACE LEAD IN GASOLINE BY MTB SPECTROPHOTOMETRY

    摘要
  • 摘要: 采用甲基百里酚蓝（MTB）作显色剂，在pH值为5．5－6．5的介质中与铅生成稳定的蓝色配合物，并用领菲罗啉和氟化铵作掩蔽剂，消除多种金属的干扰，应用于汽油微量铅的检测，取得了良好的效果。

     

    Abstract: This paper introduces a method for determination of trace lead in gasoline by MTB spectrophotometry.The MTB used as color-developing reagent reacts with lead to form the stable blue complex in the medium of pH 5.5 to 6.5,the 1,10-phenanthroline and ammoni
