| 摘 要： | 研究了离子选择性电极标准加入法的测量误差与标准溶液加入量的关系。从理论上导出了离子选择性电极一次标准加入法测量结果的相对误差计算公式。当加入标准溶液使试液增加的浓度等于试液原来的浓度，测量结果的相对误差最小。

| Abstract: | The relation between the measuring error of standard addition method for ion selective electrode and the added amount of the standard solution was studied. The calculating formula for the measuring relative error of standard addition method of ion selective electrode was obtained. The relative error of the measuring result is the minimum when the increased concentration of the sample solution is equal to the initial concentration of the sample solution by adding standard solution. |
