摘　　要：利用电感耦合等离子体发射光谱法(ICP-AES)快速测定瓶装饮用水中的微量钴。在最佳仪器分析条件下,该方法的检出限为0.001mg·L-1,相对标准偏差(RSD)为0.41%～0.73%,回收率在92.3%～108.0%之间。该方法简便、快速、准确,结果令人满意。ICP-AES was used for the rapid determination of trace cobalt in bottled drinking water. Under the optimal instrumental analysis conditions,the detection limit was 0.001mg·L^-1 ,the RSD was in the range of 0.41%～0.73% and the recoveries ranged from 92.3% to 108.0%. The proposed method was proved to be simple,rapid and accurate,and the results were satisfactory.
