| 摘 要： | 采用离子色谱法测定大同矿区地下水总硬度,并与EDTA滴定法测定结果进行对比。通过色谱实验建立Ca2+和Mg2+的标准工作曲线,然后对大同矿区地下水样中Ca2+和Mg2+浓度进行测定,换算成以碳酸钙(mg/L)表示的硬度。结果表明两种方法测出的硬度无明显差异,并且离子色谱方便,快速,高效,避免了EDTA法存在的干扰和主观误差,可作为地下水总硬度的常规分析方法。 |

| Abstract: | The total hardness in groundwater of Datong mining area were determined by ion chromatography,and were compared the method of EDTA.The standard curve of Ca2 + and Mg2 + were established by chromatography experiments,respectively.Then the concentration of Ca2+ and Mg2+ in the groundwater sample of Datong mining area were determined,and converted into the total hardness by the formula mentioned by the paper.The results showed that there was no significant difference in the values total hardness between the tw... |
