一、前言稀土族元素在矿物中是共生的,多种稀土元素的谱线干扰十分复杂。即使对只含单一稀土元素的产品,也不能忽视谱线的干扰问题。如果忽略了谱线LaLβ_2对PrLα_1将得出纯LaB_8。化合物中含有Pr的错误判断。因此只有解决稀土元素谱线干扰问题,才能提高电子探针定性分析的准确性及定量分析的精度。关于元素谱线干扰问题许多研究工作者作了许多工作,本文集中讨论应用电子计算机自动分析程序来处理元素谱线干扰问题。二、分析方法探讨 1.稀土元素谱线干扰情况调查元素波长表或不同分光晶体的L值(分光晶体离X射线源的距离)表指出,La系元素主要存在原子序数相差2的Lβ_2与La的干扰,以及原子序数相差4的Lβ_2与La的干扰。各对干扰谱线的L值列于表1。从表1可以 First, the preface Rare earth elements in the minerals are symbiotic, a variety of rare earth elements spectral interference is very complicated. Even for products containing only a single rare earth element, we can not ignore the interference of spectral lines. Ignoring the spectral line LaLβ_2 against PrLα_1 results in pure LaB_8. The compound contains the wrong judgment of Pr. Therefore, only solve the problem of rare earth element spectrum interference, can improve the accuracy of quantitative analysis of electronic probes and quantitative analysis accuracy. Many researchers have done a lot of work on the problem of spectral line interference. This article focuses on the application of electronic computer automatic analysis program to deal with element spectrum interference. Second, the analysis of methods 1.Radiation of spectral line interference Investigation of elemental wavelength table or different spectroscopic crystal L (spectroradiometer distance from the X-ray source) table pointed out that La series elements mainly exist in the atomic number difference of 2 Lβ_2 and La , And interference between Lβ_2 and La with a difference of 4 in atomic number. The L values ​​of each pair of interference lines are shown in Table 1. Table 1 can be
