交流示波极谱滴定法在药物分析中的应用 Ⅳ.硫酸恢压敏和硫酸舒喘灵的测定

Application of AC Oscillopolarographic Titration to Pharmaceutical Analysis (Ⅳ)Determination of Mephentermine Sulfate and Salbutamol Sulfate

本文采用交流示波极谱滴定法测定硫酸恢压敏、硫酸舒喘灵两种药物的含量,该法到目前为止未见报道。与其它方法相比,具有快速准确、终点直观、用样量小的特点。溶液的颜色、产生的沉淀、片剂中的赋形剂对测定均无影响。

K_2CrO_4 titration method has been used in this papers for oscillopolarographic titration. The method is rapid with good accuracy. In the 3mol/L NH_4Ac-alcohol solution, at pH 7.0～8,5 or 0.5mol/L ethylenediamine-HCI buffer solution at pH7.8, the jndirect determination of mephentermine sulfate and salbutamol sulfate was reported by using A. C. oscillopolarographic titration with K_2CrO_4.
