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 PrimusⅡX射线荧光光谱仪对铁矿样品中的TFe、CaO、MgO、A l2O3、S iO2、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%.
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 and V2O5 in iron ore. The matrix effect was corrected by the classic a coefficient and the scattering line as an internal standard. The results are in agreement with certified values with precision of less than 10% RSD.
