摘要 采用熔融法制样,通过条件实验找出最佳熔融条件和测定条件,采用标准样品和合成标样绘制校准曲线,用X射线荧光光谱法测定萤石中CaF2、SiO2、P和S的含量。测量结果与标样标准值、未知试样化学分析值相符,CaF2、SiO2、P和S的相对标准偏差分别为0.19%、0.49%、7.55%和3.18%。 A new method for determining CaF_2, SiO_2, P and S in fluorite samples is studied by X-ray fluorescence spectrometry. In this method the samples is made by fusion,the best fusion and determination condition is found out by experiment and the working curves are made using standard and composite samples. The analytical results of the samples are comparable with those of chemical analysis and standard values and the relative standard deviations of CaF_2, SiO_2, P and S are separately 0.19%, 0.49%, 7.55% and 3.18%.
