| 摘 要： | 提出掺氧空气－乙炔火焰原子吸收光谱法测定地质样品中微量钡的新方法。使用磺基水杨酸作保护剂消除铝对钡的挥发原子化干扰，KCl作消电离剂消除钡的电离干扰。方法的检出限（K＝3）为0.04mg/L。方法已应用于测定地质标准样品中的微量钡，结果与标准值相符，对GBW07103试样测定6次，RSD为5.4%。

| Abstract: | A new method for determination of trace barium in geological samples by oxygen air acetylene flame atomic absorption spectrometry is reported in the paper. The optimum determination condition has been selected. When suitable amounts of sulfosalicylic acid and KCl are added the interference effects from the coexisting elements can be minimized. The detection limit ( K =3) is 0.04 mg/L for Ba. The method has been applied to the determination of trace amounts of barium in geological standard sample GBW 07103. The result is in agreement with certified value with precision of 5.4% RSD ( n =6). |
