摘　　要：采用电感耦合等离子体发射光谱法同时测定重晶石矿石中Ba、Sr,再将Ba换算成BaSO4.研究了基体对Sr测定的影响及消除.Ba、Sr相对标准偏差(RSD,n=12)分别为0.74%、3.3%.本方法简便、快速,准确.A method to detect Ba and Sr in barite by inductively coupled plasma-atomic emission spectrometry （ICP-AES） is proposed. The influence of the base element on the detecting of Sr and its solution is studied. The relative standard deviations （RSD, n = 12） of Ba and Sr are 0.74% and 3.3%, respectively. The method is simple, quick and accurate.
