本文介绍了海水中砷标准物质的研制过程，其中包括溶液的配制、均匀性和稳定性检验，标样的分析方法。并对标准物质的定值数据进行统计处理，两种浓度的定值结果分别为：１．００μｇ／ｃｍ３±０．０４μｇ／ｃｍ３和５１．０μｇ／ｄｍ３±２．６μｇ／ｄｍ３。两种浓度砷标准物质的稳定期均为一年
This article describes the development of arsenic reference materials in seawater, including the preparation of the solution, uniformity and stability test, standard sample analysis. The results of the two concentrations were respectively as follows: 1.00μg / cm3 ± 0.04μg / cm3 and 51.0μg / dm3 ± 2.6μg / dm3. Both concentrations of arsenic reference material are stable for one year
