摘要
介绍氧化镁标准物质的研制过程。氯化镁经重结晶提纯,与草酸铵反应制得草酸镁,将草酸镁煅烧制备成氧化镁标准物质。采用称量滴定法进行定值,实验结果表明,该标准物质定值结果准确,均匀性、稳定性良好。
The development process of magnesium oxide certified reference material was introduced. Magnesium chloride was purified by recrystallization, magnesium oxalate was prepared by the reaction of magnesium chloride with ammonium oxalate and magnesium oxide certified reference material was obtained by baking magnesium oxalate. The pureness was determined via weighing titration method. The result shows that the homogeneity and stability are good, the certification is accurate and reliable and it can meet the requirement of the actual work.
