Abstract:
Polyaniline carbon paste electrode prepared by mixing polyaniline, parrafin, graphite powder and potassium ferrocyanide a known probe in electroanalysis was analysised. The ratio of polyaniline, parrafin and graphite for the construction of the electrodes and the effect of the concentration of this conducting polymer provides enormous opportunities for electrodes modification, rapid electron transfer and direct communication to produce a range of analytical signals and new analytical applications were studied. These modified electrodes exhibited an increase in surface area and speed up of redox reaction (Bare- 0.014 cm 2 , Polyaniline-0.028 cm 2 ). Efforts have been made to discuss and explore various characteristics of PANI responsible for direct electron transfer leading towards fabrication of mediator-less sensors and electrodes reproducibility.
