重量稀释海水配制盐度标准样品方法探讨

Approaches on the Preparation of Salinity Reference Samples for Weight Diluting Seawater

海水盐度是海洋水文观测的重要内容,海洋中许多现象的发生都与盐度的分布和变化规律紧密相关,高质量盐度数据对海洋科学研究有重要作用。实验室盐度计测量是获得高精度盐度数据的有效方法,因此实验室盐度计的校准工作至关重要。"重量稀释法"是化学分析中的基本方法,海洋领域中引用该方法对高精度实验室盐度计进行校准。本文详细介绍用"重量稀释法"配制不同盐度的标准样品的原理、具体方法步骤及注意事项,并通过实验数据验证。

Salinity is an important parameter in ocean hydrological observation. Many ocean phenomenon is related with the distribution and change of salinity. High accuracy salinity data plays an important role in oceanographic research. Laboratory salimeter t is an effective approach to obtain high accuracy salinity data, so the calibration of laboratory salimeter is of great significance. Weight dilution is a basic method in chemical analysis and this method is introduced into the marine field in the calibration of high- precision laboratory salimeter. This paper mainly illustrates the principle, detailed procedure and matters need attention in the preparation of different salinity reference samples with the weight dilution method, and the method is tested with the data.
