农村生活饮用水水质检测及分析

The Water Quality Test and Analysis of Rural Drinking Water

文章采用原子吸收光谱法、AgNO3滴定法、离子色谱法和Na2EDTA滴定法分别对兴和县五个农村居民生活饮用水中重金属、氯化物、阴离子和总硬度进行测定。通过检测数据与国家生活饮用水卫生标准数据进行对比,得出十一号村的水硬度较大,其他村庄氯化物、溴酸盐等浓度较低,且所有村庄水样都未检测到重金属含量,基本上符合国家饮用水标准。

In this paper,the heavy metals,chlorides,anions and total hardness in drinking water of five rural residents in Xinghe County were determined by atomic absorption spectrometry,AgNO3 titration,ion chromatography and Na2EDTA titration.By comparing the test data with the national drinking water hygiene standard data,it is concluded that the water hardness of No.11 village is relatively high,while the concentration of chloride and bromate in other villages is relatively low.In addition,no heavy metal content is detected in the water samples of all villages,which basically meets the national drinking water standard.
