无需标准溶液的酸碱滴定计算分析研究

Calculating Analysis of Acid-Base Titration Without Standard Solution

无需标准溶液的滴定计算分析能同时求出滴定剂与被测物质浓度.本文用非线性规划问题的单纯形加速法对无需标准溶液的酸碱滴定进行了研究.单元酸、多元酸及混合酸的测定得到了比较满意的结果.

The calculating analysis of titration without standard solution is a method that can be used to determine the concentration of substance titrated and titrant at the same time. In this paper, the calculating analysis of acid-base titration without standard solution has been described for the determination of monobasic acids, polybasic acids and mixed acids with potentiometric titration and the simplex optimization method. The relative error is less than 2% for monobasic and polybasic acids and 10% for mixed acids.
