| 摘 要： | 分别研究了采用压片、熔片两种制样方法,用X射线荧光光谱法(XRF)测定了红土镍矿中的9种元素。压片法重点研究了基体效应校正,经散射线作内标和经验系数法校正后,可准确测定除二氧化硅、氧化镁外的7种元素,方法简便、快速;而熔片法着重研究了熔剂和熔样温度的选择,经基体效应校正,各分析元素的结果准确度完全可与化学法相媲美,其相对标准偏差(RSD)在0.50%～3.00%间。

| Abstract: | The 9 elements in nickel laterite ore are measured by XRF spectrometer, using pressed powder method and fused bead. For pressed powder method, after the matrix effect were corrected by the Compton scattered line Rh Ka as internal standard and experience coefficient method, the 7 elements can measure except SiO2, MgO accurately. For fused bead method, the selection for flux and fused temperature were researched emphatically, the accuracy of the measurement result can compare with chemical method, and the precision of the method (RSD) is between 0.50% and 3.00%. |
