A simple fluorometric method for the determination of salicylic acid in aluminium acetylsalicylate.
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.
