摘要
本文用原子吸收方法制定了测定刹车片中Si、Mn、Ni、Cr和Mo的快速方法。选择了最佳测定条件,研究了HCl、HNO_3和HF以及共存元素的影响。结果表明方法快速准确。
The influences of the amounts of HC1,HNO3 and HF, iron and coexisting; elements on the determination of Si,Cr,Mo, Mn and Ni in brake block have been investigated. A rapid procedure for the determination of Si, Cr, Mo, Mn and Ni in brake block by AAS has been developed. A sample is analysed with this method and national standard method ( GB223-81),t test shows no significant difference in statistics. Therefore the method is not only simple but also accurate.
