| 中文摘要: |
| 建立了采用波长色散X射线荧光光谱法测定铁矿石中TFe、SiO2、AI2O3、MgO、CaO、K2O、Na2O、TiO2、MnO、P、S和Cu等12种主次量组分的分析方法。采用LiBO2-Li2B4O7混合熔剂熔融制样，以铁矿石一级国家标准物质为校准样品，通过加入Co2O3内标、使用理论α系数法和经验系数相结合的方法校正基体效应和谱线重叠干扰。方法的准确度、精密度达到了传统化学分析方法的要求，分析时间大大缩短，具有很好的使用价值。 |
| 英文摘要: |
| A new method has been developed for the determination of 12 components including TFe, SiO2, AI2O3, MgO, CaO, K2O, Na2O, TiO2, MnO, P, S and Cu in iron ore by the wavelength-dispersive X-ray fluorescence spectrometry. The samples are fused with mixture flux of LiBO2-Li2B4O7(67:33) and the calibration samples are artificially synthesized with high purity compounds. The common background method is used for background calibration and the variable theoretical α-coefficient method is employed for matrix effect calibration. This method has the advantages of high accuracy and precision, and high efficiency, and has been applied to the routine analysis of iron ore. |
