摘要
目的：探讨两次加入滴定剂标准溶液的体积对酸碱双点电位滴定法准确度的影响。方法：根据误差传递理论，用数学方法推导出影响测定结果准确度的因素。结果：滴定剂体积Ｖ１ 固定时，Ｖ２ 越大准确度越高；滴定剂体积Ｖ２ 固定时，Ｖ１ 有一最佳范围。结论：酸碱双点电位滴定法具有简便、快速等特点，通过选择适宜的滴定剂体积能够提高测定结果的准确度。
Objective: Adding two titrant standard solution volumes affecting acid base double point potentiometric method accuracy are discussed. Methods: The factors affecting accuracy are studied using mathematic method based on error delivering theory. Results: When the titrant's volume V 1 is fixed, accuracy is higher as V 2 is bigger, when V 2 is fixed, V 1 has a best range. Conclusions: The acid base double point potentiometric method is simple and rapid. Selecting proper titrant's volume can increase the accuracy of determination results.
