对维生素C的含量测定,药品标准中均采用碘量法。碘量法不仅易受空气及氧化剂作用的影响,而且操作繁琐。我们试用旋光法测定维生素C的含量,结果满意。一、仪器与药品:WZZ—1型自动指示旋光仪,维生素C(分析纯,淄博化学试剂厂,批号:870421,870424;北京化学试剂厂,批号:870523)。
The determination of vitamin C content, drug standards are used iodine method. Iodometry is not only susceptible to the effects of air and oxidants, but also cumbersome to operate. We try to determine the content of vitamin C using the optical rotation method, with satisfactory results. First, instruments and medicines: WZZ-1 automatic indicator polarimeter, vitamin C (Analytical Pure, Zibo Chemical Reagent Factory, batch number: 870421,870424; Beijing Chemical Reagent Factory, batch number: 870523).
