一引言X射线荧光光谱法测定稀土分量是一个行之有效的方法。为了降低检出限,提高分析准确度,近几年来,国内外不断有人研究,由于电子计算机技术的广泛应用,对基体效应、谱线干扰及背景扣除等繁锁的计算都可由计算机完成,使稀土元素的X射 An Introduction X-ray fluorescence spectrometry for the determination of rare earth components is an effective method. In order to reduce the detection limit and improve the accuracy of the analysis, in recent years, there are many studies at home and abroad. Due to the extensive application of electronic computer technology, the calculations of matrix effects, spectral line interference and background subtraction can be completed by computer.
