X射线荧光光谱法同时测定铁矿石中的主次量组分

Simultaneous Determination of Major and Minor Componentsin Iron Ore Samples by XRF Spectrometry

摘要: 采用熔融玻璃片制样，选用标准样品，以经验α系数和散射线内标法校正元素谱线重叠干扰和基体效应，使用ZSX Primus Ⅱ X射线荧光光谱仪对铁矿样品中的TFe、CaO、MgO、Al₂O₃、SiO₂、P₂O₅、TiO₂、MnO、V₂O₅等组分进行测定，分析结果与标准值和化学值相吻合，12次测定的相对标准偏差小于10%.

Abstract: An X-Ray fluorescence spectrometric method with a fusion sample preparation technique has been developed for the determination of TFe、CaO、MgO、Al₂O₃、SiO₂、P₂O₅、TiO₂、MnO、V₂O₅ in iron ore.The matrix effect was corrected by the classic α coefficient and the scattering line as an internal standard. The results are in agreement with certified values with precision of less than 10% RSD.
