| 摘 要： | 采用EDTA鳌和滴定法检测阿克苏部分水样中的总硬度、钙离子浓度和镁离子浓度,并将之与国家对于饮用水硬度的标准进行比较,结果发现自来水、地下水、多浪河水总硬度在350 mg/L左右,属于高硬度水。分析不同净水方式水净化效果,结果表明经过滤装置及净水器处理后的水硬度在230 mg/L左右,硬度有所降低但依然属于高硬度水;阿克苏水质硬度较高,在饮用时需采取一定的措施降低其硬度,建议先过滤净化后烧开再饮用较为妥当。

| Abstract: | The total hardness,calcium ion concentration and magnesium ion concentration of some water samples from Aksu were determined by EDTA chelation titration,and compared with national standards for hardness of drinking water.The results turned out that the total hardness of tap water,ground water and Duolang River water ware high,about 350 mg/L.The water purification effects of different methods were analyzed,and the results indicated that water treated by filter and water purifier had a hardness of about 230 mg/L,and was still high hardness water though it was reduced.Hardness of water in Aksu was high and should be reduced through certain measures before drinking.It was suggested that water should be filtered and boiled before drinking. |
