采用石墨炉原子吸收光谱法测定湘江水中的铍，通过一系列的实验表明，该方法检测湘江水中铍的检测线性范围为0～2μg／L，加标回收率在95％～98％之间，精密度小于5％。检出限为0．00223μg／L，远远低于生活用水国家标准值0．002μg／L，结果表明石墨炉原子吸收光谱法可用于湘江水中铍的测定。
採用石墨爐原子吸收光譜法測定湘江水中的鈹，通過一繫列的實驗錶明，該方法檢測湘江水中鈹的檢測線性範圍為0～2μg／L，加標迴收率在95％～98％之間，精密度小于5％。檢齣限為0．00223μg／L，遠遠低于生活用水國傢標準值0．002μg／L，結果錶明石墨爐原子吸收光譜法可用于湘江水中鈹的測定。

Graphite furnace atomic absorption spectrometry was applied to determine beryllium ion of Xiangjiang river.The experimental results showed that the detection linear range was 0~2 μg/L with adding standard recovery of 95%~98%and relative deviation less than 5%.The detection limit was 0.00223μg/L, which was much lower than the national standard limit of 0.002 mg/L for surface water.It was proved that the method can be used to determine beryllium ion in Xiangjiang river.
