摘　　要：生活饮用水中硬度是水质监测中的一项重要指标,饮用水硬度的高低直接影响着人们的身体健康。本文采用等离子体原子发射光谱法（ICP-AES）对饮用水中的钙镁元素进行分析,并计算出饮用水的总硬度。实验过程确定了最佳测量条件,采用标准曲线法定量,样品的加标回收率为98.35%~99.35%,RSD为0.51%~2.92%,实验结果表明该方法具有简单、快速、重现性好等优点,能用于生活饮用水的检测。Drinking water hardness is an important indicator of water quality monitoring, water hardness directly affects people＇s health. The total hardness in drinking water can be determined by ICP-7510. The best measurement conditions were studied, standard curve method was used to quantify, the recoveries were 98. 35% -99. 35%, RSD were 0. 51% -2. 92%. The method has the advantages of simple, fast and good reproducibility, detection can be used for drinking water.
