摘要
采用石墨炉原子吸收法测定湘江水中的钡，通过一系列的实验表明，该方法检测湘江水中钡的检测线性范围为0～40μg／L，加标回收率为94％-98％，检测相对误差小于5％，检出限为0．022μg／L，远低于地表水国家标准下限0．7mg／L，结果表明该方法可用于湘江水中钡含量的测定。
Applied graphite furnace atomic absorption spectrometry to determine barium ion of Xiangjiang River. The experimental results showed that the detection linear range is 0-40 μg/L with adding standard recovery of 94%-98% and relative deviation less than 5%. The detection limit is 0.022 μg/L, which is much lower than the national standard limit of 0.7 mg/L for surface water. Proved that the method can be used to determine barium ion in Xiangjiang River.
