标准摘要
[中文适用范围]： 本国际标准规定了海水中总碱度的开孔电位滴定测定方法。 结果以每千克海水的摩尔数表示。 该方法适用于测定实际盐度为 30 至 40 的正常海水的总碱度水平（2 000 IJmol kg-1 至 2 500 IJmol kg-1）。 [外文原描述]： ISO 22719:2008 specifies an open-cell potentiometric titration determination of total alkalinity in sea water. The results are expressed in moles per kilogram of sea water. The method is suitable for assaying oceanic levels of total alkalinity (2 000 µmol kg –1 to 2 500 µmol kg –1 ) for normal sea water of practical salinity ranging from 30 to 40.
