摘要
建立了用电感耦合等离子体光度发射光谱(ICP-OES)法测定饮用天然矿泉水中锶的新方法。优选了试剂介质和仪器条件。方法简单、快速、灵敏度高。锶的检出限为0．0002mg/L,相对标准偏差小于2％(RSD,n=10),用于饮用天然矿泉水中锶的测定取得了满意的结果。
A new method of determining strontium （Sr） in natural mineral water for drinking by the ICP-OES is established. The medium of solution and measurement condition are optimized. Being simple, rapid and highly sensitive, the method is featured by the detection limit of 0.0002mg/L and the relative standard deviation less than 2% （RSD, n=10） . It has been applied to the determination of Sr in natural mineral water for drinking with satisfactory results.
