本文提出了一种测定二元有机碱二盐酸盐类药物含量的直线图解法,以取代传统的非水滴定法。实验以电位滴定为分析手段,滴定剂以分步等体积加入。等当点的确定同样也可采用线性回归法,数据处理仅采用一种TI-59型可编程序计算器便可完成。本文还就测定的结果是药物的生理活性部分含量,而不是盐酸酸根部分含量作了进一步的讨论。 In this paper, a linear method for the determination of binary organic base dihydrochloride drugs is proposed to replace the traditional non-aqueous titration method. Potential titration test for the analysis, titration step by step volume added. Equivalent points can also be determined using linear regression, data processing using only a TI-59 programmable calculator can be completed. This article also the results of the determination of the physiological activity of the drug content, rather than part of the acid radical was further discussed.
