计算法同时测定混合酸中各组份

STUDYT ON SIMULTANEOUS DETERMINATION OF MIXED ACIDS BY MATHEMATICAL METHOD

用一组已知标准混合酸溶液的电位滴定数据建立数学计算模型,它可对未知混合酸溶液中各成份进行测定。本法对甲酸—醋酸体系、硼酸—磷酸体系、氯醋酸—酒石酸—柠檬酸体系、甲酸—丁二酸—磷酸体系进行了测定。

A new mathematical method for simultaneous determination of mixed acids is developed. In this method a mathematical model is obtained from samples of known composition and is then used to predict the concentration of unknown samples. The experiments are performed by potentiometric titration and the volumes of titrant at certain points of pH are recorded.This method is applied to the simultaneous determination of four systems of mixed acids and the results are satisfactory。
