| 摘 要： | 测定水质总硬度最常用的是EDTA 滴定法,该法易受到多种因素的影响,而锰是重要影响因素之一。分析了锰对EDTA滴定法的影响,对比了两种掩蔽剂对不同浓度锰的掩蔽效果和对检测结果的影响。对实验结果进行了总结分析,为EDTA滴定法测定高锰水体总硬度过程中不同掩蔽剂的选择提供一定的依据。

| Abstract: | The most commonly used method for determining the total hardness of water is the EDTA titration method,which is susceptible to many factors,and manganese is one of the important factors.The effect of manganese on EDTA titration was analyzed,and the masking effect of two masking agents on different concentrations of manganese and the influence on the detection results were compared.The experimental results were summarized and analyzed,which provided a basis for the selection of different masking agents in the process of determining the total hardness of high manganese water by EDTA titration. |
