不同抗氧剂对利凡诺溶液稳定性的影响考察

Study on the Influence of Antioxygens on Stability of Rivanol Solution

目的 :考察在利凡诺溶液中分别加入抗氧剂亚硫酸氢钠、硫代硫酸钠、依地酸二钠后对其稳定性的影响。方法 :采用紫外分光光度法测定含量 ,通过加速试验比较利凡诺溶液在加入不同抗氧剂前后的稳定性。结果与结论 :亚硫酸氢钠、硫代硫酸钠、依地酸二钠均不能有效提高利凡诺溶液的稳定性 。

OBJECTIVE:To observe the influence of antioxygens(sodium hydrogen sulphite,sodium thiesulfate,disodium edetate)on the stability of rivanol solution.METHODS:The rivanol content was determined by UV-spectrophotometry,and the stability of the rivanol solutions containing different antioxygens was observed by accelerated test.RESULTS&CONˉCLUSION:Sodium hydrogen sulphite,sodium thiesulfate and EDTA can not improve the stability of rivanol solution and sodiˉum thiesulfate can reduce the stability of rivanol solution.
