摘　　要：介绍高猛酸钾溶液标准物质的研制过程。对研制的溶液标准物质进行了均匀性和稳定性考察。结果表明,该标准物质均匀性良好,定值稳定期为6个月。用称量滴定法定值,定值结果为c(1/5 KMnO4)=0.100 7 mol/kg(k=2)。该标准溶液满足二级标准物质的技术要求,已被批准为国家级二级标准物质。Preparation process of potassium permanganate solution standard material was introduced. Weighing titrimetric method was used for certification. The homogeneity and stability of potassium permanganate solution standard material were examined. The results indicated that the standard material was homogeneous and the value stated was valid for a period of 6 month. The stated value of it was c（1 / 5 KMnO4）=0.100 7 mol/kg（k=2）. The standard material meets the requirements of the secondary level of standard material and it has been authorized for the state-level standard material.
