| 摘 要： | 采用原子吸收分光光度法测定黄河水体的总硬度,钙的浓度在0.100～5.00 mg/L、镁的浓度在0.0500～2.00 mg/L范围内分别与吸光度呈线性关系,线性方程分别为A=0.045 5c+8.354×10~(-5)、A=0.514c+8.354×10~(-5),相关系数均为0.9999。黄河水样6次测定结果的相对标准偏差为1.2％,t检验结果表明,该法与EDTA络合滴定法测定结果无显著性差异。

| Abstract: | The total hardness of the water of Yellow River was determined by the method of Zeeman flame atomic absorption spectrophotometry (FAAS). The relative standard deviation is 1.2%. The results of the determination is proved to have no obvious difference by t test beween FAAS method and EDTA method. It shows that this method can meet the need of the quality control of the environmental monitoring. This method can be regarded as the reliable method to determine the total hardness of water. |
