摘要
研究水溶液溴酸根标准物质研制的方法,采用超纯水进行重量-容量法配制而成,用国家一级标准物质给该标准物质进行定值,对考察其均匀性及稳定性。稳定性时间考察10个月以上,并对不确定度进行分析评估。
Study the preparation of Bromate standard solution, which was developed by weight - volumetric method using ul- trapure water. Nominal value was valued accodding to standard materials at the national level. Its uniformity and stability was examined. Time to study the stability of 10 months or more, and the uncertainty was analyzed and evaluated.
