摘要
本文在原子吸收光谱仪的发射方式上，选择钡５５３．５ｎｍ发射线，以空气乙炔火焰为发射光源。进行了火焰发射法测钡的方法研究。全面讨论了测试条件和干扰试验，并与ＩＣＰ－ＡＥＳ、笑气乙炔ＡＡＳ，以及空气乙炔ＡＡＳ进行了比较，还讨论了乙醇的增感作用。并对出口玩具材料中的可溶性钡进行了测定比较，得到满意结果。
A method research for determination of trace barium by flame emission spectroscopy has been described,basing on the emission made of AAS.The emission line of barium is 553.5nm and the emission source is air-acetylene flame.The experimental conditions and inference experiments were discussed totally and the results were compared with the results of N2O-acetylene AAS,ICP-AES and air-acetylene AAS.The Sensibilization of ethanol was also discussed.The contents of soluble barium in materials with the export toy is made from,were also determined.The results were satisfactory.
