| 摘 要： | 将萃取与回流相结合, 建立了一种处理航空润滑油中磨损金属的新方法, 并用MPT全谱仪对磨损金属含量进行了同时检测. 该方法基本上实现了样品处理的全自动化,克服了常用方法的部分缺点, 对Zn, Cd, Cu, Fe和Pb的检出限(3σ)分别为0.084, 0.043, 0.022, 0.052和0.064 μg/g; 相对标准偏差均小于5%(n=5); 回收率为94.5%~107.4%. 对3个润滑油样品的检测结果令人满意.

| Abstract: | A novel, simple and economic sample pretreatment system based on reflux extraction was developed for the determination of wear metals in the used aviation lubricating oil by using a simultaneous microwave plasma torch atomic emission spectrometer(MPT-AES). The operating parameters for both sample pretreatment and analysis were studied and optimized. The detection limits are 0.084, 0.043, 0.022, 0.052, 0.064 μg/g for Zn, Cd, Cu, Fe and Pb, respectively. The relative standard deviations are less than 5%(n=5), and the recovery ratios of these elements are in the range of 94.5%—107.4%. The new system was successfully applied to the analysis of the lubricating oil samples. |
