航空润滑油中铜、铁、镍、铬的原子吸收光谱测定

The Atomic Absorption Spectrum Measure Ments of Cu, Fe,Ni and Cr in Plane Engine Lubricant

本文介绍用标准加入法进行航空润滑油中铜、铁、镍、铬等微量金属成分的原子吸收光谱测定,采用灰化法处理样品,避免了润滑油检测中复杂的基体校正,取得满意的结果。

In this work,by using of standard addition method a-nd greying the samples the atomic absorption spectrum measurements of trace metal elements Cu,Fe,Ni a-nd Cr in phane engine lubricant without any complicated calibration of substants have been demonstrated. The results are satisfactory.
