摘要
本文研究了北京地区739份水样的测定结果,发现水的总硬度与硫酸根、氯离子、硝酸根的当量之和呈高度相关,其关系式与水源类型有关。文中提出了适用于浅井水、深井水及地面水数据核查的回归方程。
739 drinking water samples in Beijing area were analyzed. Statistical relation between the total hardness of water and the sum of eqvivalents of sulfate, chloride, and nitrate was found significant. They were influenced by different type of water sources.The regression equations for shallow well, deep well, and surfacewater were given. The equations can be used for analytical quality control of individual water sample
