Certain wear metals (Fe, Cr, Ni, Cu and Zn) of various lubrication oils were determined by means of ICP-OES and FAAS. The kerosene dilution method, which is used widely together with ICP-OES, was applied with both methods here. Calibration standards were made from a commercial organo-metallic standard. Our aim was to clarify the possibility of using the quick kerosene dilution method together with FAAS for a rapid check for certain indicator metals. Metal determinations with FAAS were accurate enough for quantitative work in machine condition diagnostics and waste oil characterization, when compared with those with ICP-OES.
采用电感耦合等离子体发射光谱法（ICP-OES）和火焰原子吸收光谱法（FAAS）测定了各种润滑油中的某些磨损金属（铁、铬、镍、铜和锌）。本文将两种方法都采用了与ICP-OES一起广泛使用的煤油稀释法。校准标准由市售有机金属标准制成。我们的目的是阐明将快速煤油稀释法与FAAS一起用于某些指示金属快速检测的可能性。与ICP-OES测定结果相比，FAAS测定金属对于机器状态诊断和废油特性的定量工作来说足够准确。
