本文报告了用双波长联立方程分光光度法在尼泊金乙酯存在下直接测定硫酸阿托品和氢溴酸后马托品含量的方法。和目前现有方法比较,大大简化了操作,且有良好的专属性、准确度和精密度,同时,还能计算尼泊金乙酯含量等优点。本文从线性考察的合理性方面对考察方法作了一定考虑,对截距判别提出了处理方法;对双波长法的含义提出了讨论;同时讨论了方法的精度和定量信息,对双波长法的精度、定量信息提出了检验方法及指标。
This paper reports a direct method for the determination of atropine sulfate and hormo-hydrobromide in the presence of ethylparaben by dual wavelength simultaneous equation spectrophotometry. Compared with the existing methods, the operation is greatly simplified, and the specificity, accuracy and precision of the method are also good. In addition, the advantages of ethylparaben content can be calculated. This article makes some considerations on the reasonableness of the linear investigation, puts forward a solution to the intercept discrimination, discusses the meaning of the dual-wavelength method, discusses the accuracy and the quantitative information of the method, Accuracy, quantitative information proposed test methods and indicators.
