| 摘 要： | 采用X射线荧光光谱法测定铁矿粉中的TFe(全铁量)、SiO2、Al2O3、P、S、CaO、MgO、MnO和TiO2等9个组分。以Li2B4O7和LiBO2(质量比67∶33)的混合熔剂熔融制样,将测量全铁量的内标Co2O3制备成均匀的Co玻璃粉,大大提高全铁量的测量准确度和精密度;加入LiNO3为氧化剂,解决了硫元素在制样过程中容易挥发的问题。与化学法相比,该法对铁矿石中主量和次量元素的测量结果满意,方法快速、简便、准确、精密度好。

| Abstract: | Nine components including TFe(total iron),SiO2,Al2O3,P,S,CaO,MgO,MnO and TiO2 in iron ores were determined by X-ray fluorescence spectrometry.The samples were fused with mixed flux of Li2B4O7 and LiBO2(67∶33).The homogeneous cobalt glass powder was prepared with CoO3 and used as internal standard to improve the accuracy and precision.LiNO3 was added as oxidizing agent to prevent sulfur from volatilization during fusion.The method provides the advantages of higher accuracy and precision,simple operation and more efficiency over the classical chemical methods. |
