Componental Analysis of Cryolite by XRF Spectrometry
摘 要
研究了冰晶石样品熔融法制样的条件,确定了熔融法制样中选用四硼酸锂和偏硼酸锂(以质量比67比33)混合作溶剂,消除熔融过程中氟元素的挥发问题,且保证混合溶剂与试样的质量比为10比1.5以形成玻璃片等试验条件,制定了利用X射线荧光光谱仪测定冰晶石中元素含量的方法.用理论α系数或基本参数法校正元素间谱线重叠干扰和基体效应,拟定的方法进行实际样品分析,其测定结果与标准值或化学值相符.
Abstract
Conditions of fusion of cryolite sample for XRFS analysis were studied,and a mixture of lithium tetraborate (67 g) and lithium metaborate (33 g) was used as flux to avoid loss of fluorine during the fusion process.Mass ratio of flux to sample of 10 to 1.5 was taken in the fusion to give a glassy disc-shaped melt,suitable to be used for XRFS analysis.Matrix effect and interferences due to overlapping of spectral lines of elements were corrected by the theoratical α coefficient and the basic parameters.By the proposed method,3 main components (F,Al and Na),and 5 main impurities (SiO2,Fe2O3,SO3,CaO and P2O5) were determined.In applying the method to the analysis of 4 standard samples or known samples,the results obtained were in consistency with the standard values or known values.
