众所周知,铍在铜合金、铝合金中已经得到应用,而在黑色金属中铍的应用刚刚开始。在合金钢中加入一定量的铍,可以增强钢材的硬度,同时也可以防止硫对合金的危害,大大地改善合金钢的性能。测定不锈钢中铍,若采用化学重量法,要经过沉淀分离、过滤洗涤、灼烧称重等繁琐手续,分析周期较长。因此,我们采用了原子吸收分析法。据有关文献报导,铍在空气—乙炔焰中测定效果很差,而在一氧化二氮—乙
It is well known that beryllium has been used in copper alloys and aluminum alloys, and the application of beryllium in ferrous metals has just begun. In alloy steel by adding a certain amount of beryllium, can enhance the hardness of steel, but also can prevent the harm of sulfur on the alloy, greatly improving the performance of alloy steel. Determination of beryllium stainless steel, if the use of chemical gravimetric method, to be separated by precipitation, filtration and washing, burning weighing and other cumbersome procedures, the analysis cycle is longer. Therefore, we use atomic absorption spectrometry. According to the literature, beryllium is poorly measured in the air-acetylene flame, whereas in nitrous oxide-B
