总硬度测定中缓冲溶液配制方法的改进实验

Preparation of Buffer Solution in Measurement of Total Hardness

阐述了测定地下水和地面水总硬度时缓冲溶液配制方法的改进,经对比试验,可用于水质样品的分析测定工作。

An improved method to prepare buffer solution for measuring total hardness of surface water and groundwater was introduced. This method can be used in analytic determination of water quality through contrast experiment.
