摘　　要：用氢氟酸-高氯酸消解体系分解样品,建立了石英砂中铁、钛、镁、锰、锌、铜、铅、砷、镉、镍、铬、钴、锑、铝、钡等15种杂质元素的电感耦合等离子体发射光谱测定方法。系统研究了氢氟酸-高氯酸和氢氟酸-硫酸消解体系对测定结果的影响,对氢氟酸、高氯酸试剂的用量、消解温度和仪器条件等参数进行了优化。选取石英砂样品进行加标回收试验,方法平均回收率为90.4%-110.7%,相对标准偏差（RSD,n=6）小于5.0%,检出限为0.17-0.88μg/g。方法简单、快速,样品一次前处理即可完成多种元素的检测,灵敏度高,精密度好,可满足生产企业对石英砂产品和原料杂质含量的控制。A method was developed to determine of Fe,Ti,Mg,Mn,Zn,Cu,Pb,As,Cd,Ni,Cr,Co,Sb,Al and Ba in the quartz sand by inductively coupled plasma-atomic emission spectrometry（ICP-AES）.The effect of the HF-HClO4 and HF-H2SO4 digestion systems to the results was investigated.Moreover,the conditions of acid consumption,digestion temperature and instrumental conditions were optimized.The detection limits for the elements were 0.17-0.88 μg/g and the recoveries of the method were 90.4%-110.7% with RSD（n=6） of less than 5.0%.The method possesses the advantages of simple operation,high sensitivity,good precision and is suitable for routine analysis of impurity elements in the quartz sand.
