本文介绍了用氧化镁吸收油热分解的制样方法,而后用能量色散X射线荧光分析法测定油中微量元素。该方法避免了复杂的基体效应校正,作者用此方法测定了油中七种元素,其探测限为几个μg/g。
This article describes the sample preparation method for the thermal decomposition of oil absorbed by magnesia, and then the determination of trace elements in oil by energy dispersive X-ray fluorescence spectrometry. This method avoids the complex matrix effect correction, the authors used this method to determine the seven elements in the oil, the detection limit of several μg / g.
