摘　　要：本文在研究的时候,主要使用火焰原子吸收光度法以及盐酸溶解灰岩样,在使得燃烧器旋转90。的时候,使光束能够垂直穿过火焰,在特定工作环境中,选快速简便测定灰岩样中镁的相关含量。本方法在具体应用的时候,能够使得原子吸收分光光度法测定氧化镁的范围得以扩展,对生产成本有效减少,在进行测试的时候,可替代EDTA容量滴定法的方式,使得灰岩中的镁含量在测定的时候能够更加有效。In the study, the flame atomic absorption spectrophotometry and hydrochloric acid dissolved limestone samples were used to make the burner rotate 90. When the beam is allowed to pass vertically through the flame, it is quick and easy to determine the relevant content of magnesium in the limestone sample in a specific working environment. In the specific application, the method can expand the range of magnesium oxide by atomic absorption spectrophotometry, and effectively reduce the production cost. When testing, it can replace the EDTA volumetric titration method to make magnesium in limestone. The content is more effective at the time of measurement.
