饮用水浑浊度与pH值的相关性

Correlation between the Turbidity and pH Value of Drinking Water

目的探讨饮用水中浑浊度与pH值之间的相关性。方法分别测定饮用水中pH值、浑浊度和水样放置24h后的实验结果。结果随着饮用水中pH值的下降和放置时间的增加,饮用水中浑浊度呈上升的趋势,二者的相关系数为r=-0.97,P<0.01。结论饮用水中浑浊度和pH值呈显著负相关。

[ Objective] To explore the correlation between the turgidity and pH value of drinking water. [ Methods ] The turbidity and pH value of fresh drinking water and of the water that was placed for 24 h were determined. [ Results] With the decrease of pH value and the increase of the still time, the turbidity of drinking water had an increasing tendency ; the correlation ratio was R = -0.97 （P 〈0. 01 }. [ Conclusion] The turbidity is proved to be negatively correlated with the pH value.
