The article focuses on developments of polyaniline-coated glassy carbon electrodes for pH determination of various materials. Polyaniline film was electro-polymerized on a tailor-made flat surface polished glassy carbon electrode of 1-mm diameter in a polytef holder of 1-cm diameter. The electrode was first activates in 0.5 mole per liter hydrochloric acid at 2.0 volt for 30 seconds. After this procedure the potential was cycled five times between -1.1 and +1.6 volt. Afterwards, the solution was exchanged with 0.1 mole per liter aniline in 1 mole per liter hydrochloric acid and the potential cycled 25 times between -0.2 and 1.0 volts using Potentiostat/Galvanostat Model 273. |
