摘要
提出了用ICP AES直接测定润滑油中主要磨损金属元素的分析方法。对仪器的工作条件进行了优化 ,以多元素油基贮备液配制而成的ConostanS 2 1和Conostan 75油基标样制作校正曲线 ,油样品采用煤油稀释 5倍 ,测定了润滑油中主要磨损金属元素 ,各元素的相对标准偏差RSD %均小于 1%。阐述了LeemanLabs多道ProfileICP的分析效力以及具有多元素同时测定。
An analytical method for determining wear metal elements directly by ICP-AES was proposed in this paper. The optimum condition was selected. The Conostan S-21 and Conostan 75 (oil-base standard samples) prepared by multi-element oil-base reserved standard samples were applied to make calibration curve. Oil samples were diluted 5 times by kerosene. The contents of wear metals in lubrication oil were determined by ICP-AFS. The relative standard deviation (RSD) of all elements was less than 1%. In addition, the authors represented the analytical efficacy of Leeman labs multi-track profile ICP, and its rapid and accurate characters of simultaneous multi-elemerft measurement.
