| 摘要: |
| 用熔融玻璃片制样,用理论a系数和基本参数次法校正元素间的效应,用X射线光谱仪对铝矿石样品中的Al2O3、SiO2、Fe2O3、TiO2、K2O、Na2O、CaO、MgO、P2O5、MnO、S、Pb、Zn、Sr、Sc Zr、V、Ga、Cr等19种组分进行测定。结果表明,各组分的RSD均小于9.80%,除个别组分元素的含量在检测限附近误差较大,其余组分元素含量与标准值基本吻合。该测定方法的精密度和准确度可与化学法相媲美。 |

| Abstract: |
| An X-ray fluorescence spectrometric method with a fusion technique and pressed pellet sample preparation has been established for determining Al2O3、SiO2、Fe2O3、TiO2、K2O、Na2O、CaO、MgO、P2O5、MnO、S、Pb、Zn、Sr、Sc Zr、V、Ga、Cr in bauxite.The theoretical α coefficients and compton scattered line as internal standard were used to correct matrix effect.The result shows that the RSD is below 9.80%.Expect some individuals,most of the elements match with the standards.The precision and accurracy of the methed is comparable with chemical method. |
