研究了采用碱熔试样,水洗载气,ICP——AESI 法同时直接测定包钢白云鄂博矿中的6种元素,加标回收率为95%～105%,方法精密度(n=11)为3.52～5.43,应用效率令人满意。本实验在以前的工作基础上,采用 ICP—D型高频等离子发生器和 WSP—1型平面光栅摄谱仪组成离子发射光谱仪。进行了谱线的选择,电学参数、摄谱条件等实验,通过加料回收,试样分析,结果对照,认为方法简便、快速、准确,优于化学法,能够满足生产和科研的需要。 The method of direct determination of six elements in the Bayan Obo Mine by using alkali melting sample, water washing carrier gas and ICP - AESI method was studied. The recoveries were 95% ~ 105%. The precision (n = 11) 3.52 ~ 5.43, the application efficiency is satisfactory. The experiment based on the previous work, the use of ICP-D high-frequency plasma generator and WSP-1 planar grating spectrometer composition of ion-exchange emission spectrometer. The experiments of spectrum selection, electrical parameters, spectral conditions and so on were carried out. Through the experiments of feeding, sample analysis and comparison of results, the method is simple, rapid, accurate and superior to chemical methods to meet the needs of production and scientific research.
