EDTA滴定法测定水质总硬度的改进实验

Improved Experiment on Determining Total Hardness of Water Quality by EDTA Titration Method

根据EDTA滴定法测定水质总硬度的实践经验,对EDTA滴定法进行改进,该改进方法和标准方法通过地表水、地下水以及总硬度标准样品的比对测定,实验证明改进方法测定结果准确、可靠,操作更加简便、快捷。

According to the practical experience of determining total hardness of water with EDTA titration method, this study improved the EDTA titration method. Through comparative determination of the total hardness in surface water, groundwater and the standard samples by the improved method and the national standard method, the improved method was confirmed to be more accurate and reliable, and the operation was more convenient and fast.
