Keyword(s):
The determination of the real concentration in different pharmaceutical drugs represents a very important goal of the pharmaceutical industry. The main aim of the study was to set up a simple, cheap and rapid method in order to determine both ascorbic and acetylsalicylic acid content of effervescent tablets that could be found on the pharmaceutical market, without preliminary separation or extraction. For this purpose, a very simple and reliable clock method based on two Landolt-type systems of reactions, based on potentiometric techniques, has been developed. The method has been tested on different effervescent tablets which contain ascorbic acid and acetylsalicylic acid in different mixture ratio.
