摘要
本文建立用ICP-OES测定润滑油中21种元素添加、污染、磨损金属元素的分析方法,以航煤为稀释剂对润滑油样品稀释10倍直接进样分析,优化了有机进样的仪器工作条件,各元素的回收率和稳定性良好。
Analytical method for direct determination of 21 elements such as additive elements, wear metals and contaminants was established. Lubricating oil samples were only diluted 10 times by kerosene then determined by ICPOES. The recovery is 90%～105% for the elements with precision less than 1.5%. Compared to conventional method, it＇s more simple, more rapid and higher accuracy.
