采用粉末压片-波长色散X射线荧光光谱法分析了中碱及无碱玻璃纤维中硅、铝、钙、镁、铁、钛、钾、钠、砷、氟等10种主、次量元素成分含量.以6个标准样品并结合两个参考样品建立校准曲线,采用De Jongh模式方程有效校正玻璃基体中元素间的吸收-增强效应和重叠效应.该方法测定10个元素的精密度和准确度均较好,其相对标准偏差在0.35%~2.86%之间,对实际样品的分析结果与化学法相吻合,可应用于玻璃纤维中多元素成分的快速分析.

Rapid determination of major and minor element in medium-alkali and non-alkali glass fibre was fulfilled by the wavelength dispersive-X-ray fluorescence spectrometry.Sample disc was prepared by pressing the powdered sample in a mould.Major and minor elements,including Si,Al,Ca,Mg,Fe,Ti,K,Na,As and F,were determined by the presented method rapidly and simultaneously.Six standard samples and 2 reference samples were used in the preparation of calibration curves,and the α-coefficient of the De Jongh mode theory was used to correct the inter-element absorption-enhancement effect and spectral overlapping effect of the glass matrix.Precision of this method was tested and RSD′s for all the 10 elements determined were in the range from 0.35% to 2.86%.The results obtained by this method were in consistency with the results given by chemical methods.
