Abstract
The application of direct current differential electrolytic potentiometry (dc DEP) to the titration of caffeine in acetic anhydride‐toluene mixture has been investigated. A very stable low current source has been constructed to polarize the antimony electrodes. The behavior of these electrodes during the titration of caffeine has been examined. Caffeine in commercial samples like tea, Pepsi as a beverage and Prontopyrin, a proprietary drug, was extracted in chloroform and determined by dc DEP.
