Abstract
A simple, rapid fluorometric method for the determination of salicylic acid in aluminium acetylsalicylate is presented. The method is based on the dissolution of aluminium acetylsalicylate in sodium fluoride-hydrochloric acid solution, filtration and dilution with buffer solution pH = 4 followed by the fluorometric determination of the liberated salicylic acid. The method was applied successfully to the determination of salicylic acid in aluminium acetylsalicylate tablets.
摘要
本文提出了一种简单、快速的荧光分析法，用于测定乙酰水杨酸铝中的水杨酸。该方法基于乙酰水杨酸铝在氟化钠-盐酸溶液中的溶解，过滤并用pH = 4的缓冲溶液稀释，然后荧光法测定释放出的水杨酸。该方法已成功应用于乙酰水杨酸铝片剂中水杨酸的测定。
