| 摘 要： | 水质硬度的测定方法很多，本研究选用离子色谱法和EDTA络合滴定法对地下水和地表水样品分别进行测定，结果表明离子色谱法相对于传统的EDTA络合滴定法有干扰小，对环境污染少的优点，但水质测定的国标方法中没有该方法，因此建议可用离子色谱法测定水质硬度。

| Abstract: | There are many methods for determination of water hardness, this study used ion chromatography and EDTA complexometric titration of groundwater and surface water samples were determined. The results show that ion chromatography with interference is smaller rel- ative than the EDTA complexometric titration, the advantages of less environmental pollution. But the national standard method for water quality determination without the method, therefore, Water hardness can be measured by using ion chromatography |
