中文摘要:

      采用复合熔剂玻璃熔片法制备样片，X射线荧光光谱法测定碳酸盐岩样品中SiO₂、Fe₂O₃、Al₂O₃、TiO₂、CaO、MgO、K₂O、Na₂O、MnO和P₂O₅等主次成分.使用理论α系数校正基体效应，国家一级标准物质验证，方法简单快速.测量结果各元素相对标准偏差（RSD，n=12）低于10%（除含量在检出限附近的元素外），检出限低，能够符合地矿行业的要求.

英文摘要:

      A method for the determination of major and minor elements including SiO₂, Fe₂O₃, Al₂O₃, TiO₂, CaO, MgO, K₂O, Na₂O, MnO and P₂O₅ in carbonate rock samples by Axios X-ray fluorescence spectrometry with mixed flux fusion pellets was proposed. The matrix effect was corrected using the theoretical alpha coefficient. The method was verified by the first-class national standard material. The method is simple and rapid. The relative standard deviation(RSD, n=12) of each element in the measurement results was less than 10% (except for the contents of elements near the detection limit), and the detection limit was low, which can meet the requirements of the geological and mining industry.
