直接进样原子吸收法测定润滑油中铁含量

Direct Determination of Iron in Lubricating Oil by Atomic Absorption Spectrometry

本文介绍了用石油溶剂稀释样品,直接用空气/乙炔火焰原子吸收光谱测定润滑油中铁含量的方法。当样品溶液的粘度与标准溶液的粘度基本一致时,得到了较理想的回收率和精密度。

In this paper, the direct determination of iron in lubricating oil by atomic absorption is presented. In the spectrometry an air-acetylene flame is used after the samples have been diluted with petroleum solvent. When the viscosity of the sample solution is almost identical with the viscosity of the standard solution, the rate of recovery and precision are satisfactory.
