用原子吸收测定铍多数介绍用氧化亚氮—乙炔焰。资科[1]中曾报告用氧屏蔽空气—乙炔焰测定铍灵敏度可达0.03ppm。这种火焰具有较高的温度,并且有一定的还原性,抗干扰性强。我们对资料[1]中所报导的燃烧器进行了改造,使之适合于SP—90型原子吸收分光光度计使用,对
Determination of beryllium by atomic absorption most of the introduction of nitrous oxide - acetylene flame. It has been reported in the literature [1] that oxygen-shielding air-acetylene flame beryllium sensitivity of up to 0.03ppm. This flame has a higher temperature, and a certain degree of reduction, strong anti-interference. We modified the burner reported in [1] to make it suitable for SP-90 atomic absorption spectrophotometers.
