摘要
研究了氢氟酸酸溶法处理样品,直接用电感耦合等离子体-原子发射光谱法(ICP-AES)测定高纯石英砂中硼、磷微量杂质元素。通过优化仪器参数,利用软件扣除背景等方法,成功的消除了基体效应。方法用于高纯石英砂中硼和磷的测定,同时对一个土壤标准物质进行了检测对照,实验结果显示,B和P校准曲线的线性关系好,回收率范围在93.33%—105.00%之间,相对标准偏差均小于1%,对照实验结果与标准参考值无显著性差异。方法具有分析速度快、准确度高、精密度好、检出限低的特点,适用于高纯石英砂等材料中B、P含量的同时测定。
A method for the simultaneous determination of boron and phosphorus in purifying high grade quartz sand by ICP-AES has been proposed.The influences of different sample pretreatment techniques have also been studied,and hydrofluoric acid is chosen as a solvent for sample pretreatment.Optimization of the parameters of apparatus and deduction of backdrop by software were all described and discussed to eliminate matrix effects.The method was applied to the simultaneous determination of boron and phosphorus in purifying high grade quartz sand and a standard sample,the relative standard deviations（RSD） are all no higher than 1%,and the recovery is in the range of 93.33%—105.00%.The method is convenient and rapid with good precision and accuracy.
