摘要

由于溴酸盐的毒性，它的分析对水和食品质量的评价具有特别的意义。离子色谱等分析仪器已用于测量溴酸盐，需要标准溶液进行仪器校准。建立了以标准溶液为原料的溴酸钾的测定方法。本文介绍了采用综合不确定度评价的溴酸盐标准溶液的认证和长期稳定性监测。碘酸钾的稳定性也作为附加信息提出。

Certification and long-term stability of bromate ion standard solution

The analysis of bromate is of particular interest for the assessment of water and food quality due to its toxicity. Analytical instruments such as ion chromatography have been used to measure bromate and require standard solutions for instrument calibration. A measurement method for potassium bromate as the source material of the standard solution has already been established. This paper describes the certification and long-term stability monitoring of bromate ion standard solutions with comprehensive uncertainty evaluations. The stability of potassium iodate is also presented as additional information.

期刊介绍： Accreditation and Quality Assurance has established itself as the leading information and discussion forum for all aspects relevant to quality, transparency and reliability of measurement results in chemical and biological sciences. The journal serves the information needs of researchers, practitioners and decision makers dealing with quality assurance and quality management, including the development and application of metrological principles and concepts such as traceability or measurement uncertainty in the following fields: environment, nutrition, consumer protection, geology, metallurgy, pharmacy, forensics, clinical chemistry and laboratory medicine, and microbiology.
