摘要
用差热和热（失）重法、ｐＨ值检验、离子色谱等分析方法考察和证实了Ｃｌ－对平菲尔特管重量法测定化合水（Ｈ２Ｏ＋）的干扰，研究其影响规律，提出用系数校正方法可获得Ｈ２Ｏ＋的准确结果。方法用于含氯深海沉积物和大洋多金属结核标准物质中Ｈ２Ｏ＋的定值分析。
Interferences of chlorine on determination of combined water (H 2O +) by Penfield gravimetry were investigated with differential thermometry, thermogravimetry and ion chromatography. A method based on correction coefficient for the interference correction was put forward and has been applied to the determination of H 2O + in deep sea sediments and polymetallic nodules with satisfactory results.
