提出一种更适合于海水pH测量的海水pH标准物质，对小批量制备该标准物质的制备方法及其定值方法进行探索研究。采用分光光度测定法测定海水pH标准物质的pH值，对该批海水pH标准物质分别抽取一定数量的样品采用F检验法和t检验法进行了均匀性检验和稳定性考核。结果表明，该批以人工海水为介质的海水pH标准物质混合均匀，常温条件下保存六个月是稳定的。

This paper proposes a kind of seawater pH standard material more suitable for the measurement of pH in seawater, and studies the methods of preparation and setting method of small batch process for the preparation of the standard material. The pH value in seawater refer-ence material determined by spectrophotometry is carried out to evaluate the homogeneity and stability of the seawater pH standard material pre-pared by F test and t test method. The experimental results show that both homogeneity and stability, in six month at room temperature, of this seawater pH standard material in artificial seawater are good.
