摘要
采用滤纸制样,用X射线荧光光谱法对卤水中的钾钠钙镁硫进行测定。移取定量的卤水样品滴到已氟化锂环为底拖的滤纸上,再将滤纸和氟化锂环压制成型,上机测定。使用化学方法定值的卤水样品作为人工标准样品,建立校准曲线。本方法的准确度达到了化学分析的要求,相对标准偏差(RSD)<6%,测量值与化学法结果吻合。
In this work,determination of K,Na,Ca,Mg and S in brines was investigated by X-ray fluorescence spectrometric(XRF)using filter paper as preparation technique.A specified volume of brine was transferred to filter paper which fixed by lithium fluoride ring,then compressed into shape before analyzed.Certified brine was used as artificial standard sample which quantified by chemical method.The calibration curve was established.The accuracy of this method could meet the requirement of chemical analysis.The relative standard deviation(RSD)was less than 6%.The results were consistent with those obtained by chemical method.
