| 摘 要： | 针对用双球管重量法测定化合水（Ｈ２Ｏ＋）时试样中的Ｃｌ－对测定严重干扰，考察了用浸洗样品除Ｃｌ－以及校正双球管中冷凝水（Ｈ２Ｏ±）中Ｃｌ－的两种消除Ｃｌ－干扰的方法。实验证明，两种方法均可行，但后者更具有实用性，测定结果准确、精密度较好。所拟方法对新研制的ＧＳＭＳ＿２和ＧＳＭＳ＿３两个深海沉积物标准物质的化合水进行测定，结果与初定值相符。

| Abstract: | To eliminate the serious interference from Cl - in determination of H 2O in deep sea sediments by Penfield tube gravimetry, two methods have been developed. One is based on eliminating the interference by leashing_out Cl - from the sample and the other is based on subtracting the contribution of Cl - collected in the condensed water by Penfield tube gravimetry. The results show that the latter method is more practical, accurate and precise. This method has been applied to the determination of H 2O in deep sea sediment reference materials (GSMS_2 and GSMS_3) with satisfactory results. |
