The determination of the mass fractions of bromide, sulfate, and lead as well as the isotopic composition of the lead (expressed as the molar mass and the amount fractions of all four stable lead isotopes) in an aqueous solution of sodium chloride with a mass fraction of 0.15 g/g was the subject of this comparison. Even though the mass fractions ranged from 3 μg/g (bromide) to 50 ng/g (lead), almost all results reported agreed with the according KCRVs. == Main text To reach the main text of this paper, click on Final Report [https://www.bipm.org/utils/common/pdf/final_reports/QM/K122/CCQM-K122.pdf] .

CCQM-K122“盐溶液中的阴离子杂质和铅”

在质量分数为氯化钠的水溶液中，测定溴化物，硫酸盐和铅的质量分数以及铅的同位素组成（表示为摩尔质量和所有四个稳定的铅同位素的含量分数）该比较的主题是0.15g / g。即使质量分数范围从3μg/ g（溴化物）到50 ng / g（铅），报告的几乎所有结果都与相应的KCRV一致。==正文要访问本文的正文，请单击最终报告[https://www.bipm.org/utils/common/pdf/final_reports/QM/K122/CCQM-K122.pdf]。请注意，此文本显示在BIPM密钥比较数据库kcdb.bipm.org/ [http://kcdb.bipm.org/]的附录B中。最终报告已通过CCQM的同行评审并批准发布，
